Using APIs With PHP? Here Are Your Classes

Kerasiotis Vasileios — Mon, 23 Nov 2009 19:04:13 +0000

Do you want to use an API but you are too lazy to write your own code to handle the requests? If you code in PHP as I do, then you will definitely need these classes. By using the classes listed here you will be able of using a great number of web services with an easy and documented way.

PEAR

We couldn’t write a post about PHP classes without PEAR. PEAR stands for “PHP Extension and Application Repository” and the Web Services category is the place to get ready made classes for:

Akismet
Amazon
Blogging
Compete
Delicious
Digg
eBay
Facebook
Google
Twitter
Yahoo
Youtube

and many more.

Even though PEAR is a great resource for web services related classes, sometimes you might want to use another class that doesn’t rely on PEAR to do the job or a more sophisticated one. The list that follows has PHP classes for different web services.

Content Management Systems Without The Need Of A Database

Kerasiotis Vasileios — Sat, 07 Nov 2009 19:54:01 +0000

Yesterday, there was a post in my favorite forum, asking for a very simple cms that needed no database to operate and to be able to run on a very old server that supports an old PHP version. Personally, I don’t use flat file CMSs but maybe some people be in need for one. So, i compiled this list in order to help anyone searching for database-less content management systems.

LotusCMS

LotusCMS, previously named as ArboroianCMS is a clean and easy to learn cms. It features templates for both frontend and backend, WYSIWYG editor (TinyMCE), files management and basic editing of pages and menu. The admin panel lucks some speed though.

Pivot

Pivot is a full featured cms with focus on weblogs and journal sites. You can create many blogs that have their own urls, entries and settings from the admin interface and manage pingbacks, feeds and many aspects of the blog. There are also available extensions and themes for you to use. Pivot supports more than 30 languages and allows you to customize your blog from top to toe. Definitely suggested for advanced users but might scare amateurs.

SkyBlueCanvas

SkyBlueCanvas is not just another choice for a database-less cms. This is a state of the art CMS that I also suggest as well. It uses 2 WYSIWYG editors (wymeditor and TinyMCE) in the default download package, it allows you to totally customize your site and every aspect of a page. For example you can set the metadata of a page, choose if you want this page to be included in the feed and set a page as a child of another page. You can also set the page to load to a specific module or all of the modules. There are ready templates and modules to download from the main site and use for free.

pluck

Pluck, is one of the easiest systems around. It supports a lot of languages and you will learn to use it in minutes. There are some ready to use modules and you can build your own assuming you have a good knowledge of PHP. You can manage files and images through the Albums module and set the way each module is displayed and where. Pluck also provides a trash bin where you can keep your deleted pages and content in case you need to restore them. TinyMCE is also used here.

CuteNews

CuteNews is one of the most popular flat file CMS out there despite it’s difficult to understand philosophy. There are a lot of customizations that can be made to deliver original designs and functionality. CuteNews requires you to register the CMS in order to remove the “powered by” lines.

LightNEasy

LightNEasy comes in 2 flavors. One that uses SQLite and one that uses files to store it’s data. It produces static HTML or PHP files that make it extremely fast to deliver content. It uses a type of in-line editing with FCKEditor and everything is managed through a simple panel that appears when you click the “tools” icon. I would recommend this to anyone that wants a CMS which produces static files.

FlatPress

Reminds you of something? Yes, FlatPress is what Wordpress is but for the “flat files” world. It uses Smarty for templating, it supports plugins and widgets which can be positioned in a drag n drop style and allows you to add them on the number of bars (like sidebars on WP) available from your template. It uses a BBCode editor and can produce human friendly URLs too. Great tool and also suggested!!

Other CMS

Some other CMS that come into my mind are:

PageLime is a hosted sollution that some of you can also use.

PHP Certifications. Where, Why And, How To Get Them

Kerasiotis Vasileios — Sat, 17 Oct 2009 16:10:04 +0000

Becoming a certified PHP developer, does not mean that you become a better developer but, it can surely give you some more chances to get the job. We tried to do a little research about PHP certifications, where to get one, what it takes to get one and why you need it. We also tried to find some online tests for you in order to prepare yourself before you actually go for it.

Where?

Zend

The industry’s standard can not be anything else than Zend’s Certification. Zend has been running the PHP certification program for more than 4 years and has certified nearly 5000 PHP developers. Actually, there is a contest running at the Zend site that will reward the 5000th certified developer with $5000. This is what they say:

We are rapidly approaching the 5000 PHP Zend Certified Engineer and we would like to give the 5000th person to achieve this prestigious accomplishment a special gift of $5000 in Zend Training Units and if we reach this milestone before ZendCon09 – a free entry pass to the conference!

There are guides and online exams that can help you prepare yourself to get the certification but you have to pay some money to get to them except the Zend Framework Certification study guide that comes free of charge.

There are 2 ways to get the certificate. The first one is by purchasing the examination from the Zend online store and the second one is by scheduling an exam with Pearson Vue, the company with which Zend certifications are executed.

Upon certification, you are listed to the Zend Yellow Pages, where a lot of employers look into for PHP developers and you get special discounts on Zend PHP conferences worldwide.

W3Schools

W3Schools has been a web development resource heaven for many years now. It is not luck that it is the first site to visit for most of people who want to learn web technologies and development. Recently, w3schools has been rolling out a PHP certification program. You can take the exam online and you should be supervised by a person that you select so, you have to choose a supervisor wisely in order to add credibility to your certificate. This does not add value to the certification though IMHO.

The examination consists of 70 multiple choice or true/false questions about PHP (it requires fundamental knowledge of SQL too) and you have 70′ (minutes) to complete the test. To become certified, you have to have 75% of the questions answered correct and, if you get more than 95% you get an excellency degree. The service will inform you about your pass/fail status immediately after the end of the examination and if you have passed the exam, you will be sent a PHP developer certificate. Your supervisor should sign the certification which, you can use to prove your PHP knowledge. You can verify your certification online at a unique URL that the certificate points to.

The w3schools certification costs $75 and you can pay by Paypal or credit card.

Brainbench

Brainbench is dedicated to helping organizations use assessment science to predict employee success. Using the Brainbench assessment platform, companies improve hiring and retention, boost training success, enhance customer satisfaction, and increase profitability. One of the ways to do this, is by certifying several aspects of job criteria. Brainbench has tests for you to certify your knowledge for nearly anything from aerospace to programming and of course, for PHP.

You can take the examination online for $49.95 .

ExpertRating

ExpertRating is an ISO 9001:2000 company that offers hundreds of popular certifications and tests which are suitable for students, professionals, job seekers and companies.

ExpertRating tests consist of timed, multiple choice questions with one or more correct answer/s to each question. Each test covers basic to advanced questions on each topic. The test taker should keep in mind that the knowledge of applied skills gained through real work experience is emphasized rather than theoretical knowledge. For achieving certification the test taker must score at least 50% marks. Clearing the test with a score of 80% or more will be credited as a distinction and mentioned on the certificate of accomplishment.

To get PHP certified with ExpertRating, you have to pass a 40 multiple choice questions test. You have 45 minutes to answer all questions. The certificate costs $9.95

OST

In OST’s unique online Learning Sandbox®, students have access to their own web programming and Unix shell-based database environments where they will apply new skills as they are presented by completing real-world projects.

Completion of the 4-course series earns students a Certificate of Professional Development from the University of Illinois Office of Continuing Education. All courses are certified by the University of Illinois Department of Computer Science, and students receive Continuing Education Credits upon completion of each course in the series.

The PHP/SQL Programming Certificate series is comprised of four courses covering beginning to advanced PHP programming, beginning to advanced database programming using the SQL language, database theory, and integrated Web 2.0 programming using PHP and SQL on the Unix/Linux MySQL platform.

The certificate costs $398

What does it take?

To become a certified PHP developer, besides PHP knowledge, you might need to be aware of :

HTML
SQL (MySQL most commonly)
Web administration
XML

Why?

Because as stated on the top of this post, being a great PHP developer sometimes might not be enough. Sometimes, you have to prove your knowledge to an employer to get the job and, being a PHP certified developer is one great way. Employers from around the world can find you easier since, most of the times, your name will be listed as a PHP developer on pages associated with employers.

OK I like it. Where do i start?

Here is a good list of tests and quizzes to help you get accustomed with most of the exams above:

The Manual – Needless to say that this is the best book to read
PHP Quiz @ w3schools
SQL Quiz @ w3schools
Prepare for Zend Certificate – A very useful slide-show about Zend Certification
Passing the Zend Certification Exam - A blog post from Ben Ramsey

I hope this post is informative and that it will help you to get better job opportunities with PHP.

Using Bing’s API To Create A Custom Search Engine

Kerasiotis Vasileios — Wed, 14 Oct 2009 15:44:38 +0000

Microsoft’s search engine Bing, is a getting more popular each day. Microsoft has released a REST API for Bing and we are going to use it to create a custom search engine. Before we go on coding, we need an API key from Bing. Normally you should be able to get one from http://www.bing.com/developers/appids.aspx but at the time this post was written, Bing’s site had some issues with most of it’s features. The issues should be fixed by the time you read this post though.

To get an API key, you have to click on “Create an AppId” link. If you are already logged in, then you will be presented with a screen requiring you to fill in some info about your application. The information needed is:

Application name
Description
Company name
Country/region
Email address

When you have successfully completed the preceding steps, the Your AppIDs page appears, displaying your new AppID as well as any others you have created previously.

The Challenge

We want to create a search engine that will query the Bing API and will be able to display normal search results and a more link with a drop down menu with more features. The “more” drop down menu will support features like:

Video Search
Translation Service
Spelling Service
Phonebook Service
Answers Service
Images Search

The results should be displayed using AJAX.

Sketch it first

As always, we should first get a paper and a pencil and start drawing. Your favorite image editing program should do the job too. Here is how our application will look like:

The Tools

We will be using PHP for the communication between our application with Bing’s API. Results and the pager will also be formated serverside. For the dropdown menu, we will be using YUI’s button utility. This utility will allow us to transform a select element to a nice skinable dropdown menu.

The Markup

Here is the HTML code needed for our application:


GooBingoo!

Our options are marked in a select element and each option holds a value of SELECT_ID-NUMBER. This is for the button menu utility to understand the markup of our dropdown menu.

The JavaScript

We create the dropdown menu with this code:

YAHOO.util.Event.onDOMReady(function () {
 var Button = YAHOO.widget.Button;
 var onMenuRender = function (type, args, button) {
 button.set("selectedMenuItem", this.getItem(0));
 };
 var onSelectedMenuItemChange = function (event) {
 var oMenuItem = event.newValue;
 this.set("label", ("" +
 oMenuItem.cfg.getProperty("text") + ""));
 switch(oMenuItem.cfg.getProperty("text")){
 case "Web":
 search('web');
 break;
 case "Images":
 search('image');
 break;
 case "Video":
 search('video');
 break;
 case "Phonebook":
 search('phonebook');
 break;
 case "Answers":
 search('answers');
 break;
 case "Translate":
 search('translate');
 break;
 case "Spell":
 search('spell');
 break;
 }
 };

var oMenuButton1 = new Button({
 id: "menubutton-1",
 name: "menubutton-1",
 label: "Select An option",
 type: "menu",
 menu: "searchoptions",
 container: "searchoptions-container"
 });

 /*    Register a "selectedMenuItemChange" event handler that will sync the
 Button's "label" attribute to the MenuItem that was clicked.*/

 oMenuButton1.on("selectedMenuItemChange", onSelectedMenuItemChange);

});

Now lets break down the code to explain what we are doing. First we need to create the dropdown menu with our search engine options:

//We wait until DOM is ready to be scripted
YAHOO.util.Event.onDOMReady(function () {
//and we create a button
 var Button = YAHOO.widget.Button;
//then we need to set the first option of the select element as selected
 var onMenuRender = function (type, args, button) {
button.set("selectedMenuItem", this.getItem(0));
 };
//When the menu selection changed..we update the value shown
 var onSelectedMenuItemChange = function (event) {
 var oMenuItem = event.newValue;
 this.set("label", ("" +  oMenuItem.cfg.getProperty("text") + ""));
//Here we go through all options to see which was chosen.
 switch(oMenuItem.cfg.getProperty("text")){
case "Web":
search('web');
break;
case "Images":
search('image');
break;
case "Video":
search('video');
break;
case "Phonebook":
search('phonebook');
break;
case "Answers":
search('answers');
break;
case "Translate":
search('translate');
break;
case "Spell":
search('spell');
break;
}
 };

var oMenuButton1 = new Button({
 id: "menubutton-1",
 name: "menubutton-1",
 label: "Select An option",//We add another option here to display some info for the user
 type: "menu",  //The type of the button
 menu: "searchoptions", //The id of the select element
 container: "searchoptions-container" //The id of the container element
 });

 /*    Register a "selectedMenuItemChange" event handler that will sync the
 Button's "label" attribute to the MenuItem that was clicked.*/

 oMenuButton1.on("selectedMenuItemChange", onSelectedMenuItemChange);

});

We could skip the switch by just doing: search(oMenuItem.cfg.getProperty(“text”)) but this way would limit us to the search method only.

The getXMLHTTP method is a simple way to get an XML object and don’t depend on browser version or type. So, this method will return an XML object on Firefox,Opera and IE:

function getXMLHTTP(){
 var A;

 var msxmlhttp = new Array(
 'Msxml2.XMLHTTP.5.0',
 'Msxml2.XMLHTTP.4.0',
 'Msxml2.XMLHTTP.3.0',
 'Msxml2.XMLHTTP',
 'Microsoft.XMLHTTP');
 for (var i = 0; i < msxmlhttp.length; i++) {
 try {
 A = new ActiveXObject(msxmlhttp[i]);
 } catch (e) {
 A = null;
 }
 }

 if(!A && typeof XMLHttpRequest != "undefined")
 A = new XMLHttpRequest();
 if (!A)
 alert('Your browser does not support ajax!');
 return A;
}

The next method is search, which does the actual requests and displays the results on the page:

var search = function(type,start,end){
 var xmlObject = getXMLHTTP();
 var url = "bing.php";
 url += "?type=" + type;
 url += "&q="+document.getElementById('searchbox').value;
 if(start && end){
 url += "&end=" + end;
 url += "&start=" + start;
 }
 url += "&sid=" + Math.random();
 xmlObject.onreadystatechange = function(){
 if(xmlObject.readyState == 4){
 if(xmlObject.responseText){
 document.getElementById('results').innerHTML = xmlObject.responseText;
 }else{
 document.getElementById('results').innerHTML = "";
 }
 }else{
 document.getElementById('results').innerHTML = "";
 }
 }
 xmlObject.open("GET",url,true);
 xmlObject.send(null);
}

Add Some Style

The CSS for our application:

#wraper{
 margin:0 auto;
 width:1024px;
}

#logo{
 width:470px;
 margin:0 auto;
}

#searchcontrols{
 width:450px;
 margin:0 auto;
 padding-top:30px;
}

#searchbox{
 width:250px;
 height:32px;
 font-size:1.5em;
 vertical-align:top;
}

#results{
 width:900px;
 margin:0 auto;
 padding:10px;
}

#pager{
 width:468px;
 margin:0 auto;
}

ul{
list-style:none;
}

.webresults li{
 margin:10px;
}

.title{

}

.answered,.translated,.spelled{
 font-size:1.8em;
 border:1px solid gray;
}

.phoneresults li{
 margin:20px;
 border:1px solid gray;
}

Bing API with PHP

This is where we will learn how to use the Bing API. The best thing about this API is that you can use 3 protocols to get the results. The protocols are:

JSON
XML
SOAP

So, you can actually use any way that you are familiar with. In our case, we will be using the JSON protocol. PHP allows us to work with JSON encoded data very easily. For example a typical call to the Bing API with JSON looks like this:

$request ='http://api.search.live.net/json.aspx?Appid=API_KEY&sources=SOURCE&SOURCE.Count=NUMBER_OF_RESULTS&SOURCE.Offset=OFFSET&query=QUERY';
$response = file_get_contents($request);
$jsonobj = json_decode($response);

Please note:

API_KEY – The API key you got from Bing’s developer center.
SOURCE – What you will be searching for. There is a great number of sources to use. These are:
- Ad – Use the Ad SourceType to incorporate advertisements into your application.
- Image – The Image SourceType returns a list of images relevant to the query term. Image results contain properties about the image media file such as width, height, and file size, along with the URL for the page that contains the image.
- InstantAnswer – The InstantAnswer SourceType enables you to get single, authoritative answers to questions such as: What is 789*12?
- MobileWeb – The MobileWeb SourceType returns mobile Web search results – primarily Extensible Hypertext Markup Language (XHTML) or Wireless Markup Language (WML) pages relevant to the queried term.
- News – Search news.
- Phonebook – The Phonebook SourceType enables you to view details about a business for which you are searching as if they were a phonebook entry.
- RelatedSearch – Use the RelatedSearch SourceType to view searches that provide information in which you might be interested, based on your current search.
- Spell – When a query is sent to the Spell SourceType, alternative spellings for the query based on a number of criteria are proposed.
- Translation - The Translation SourceType translates a term or a small block of text (three sentences or less) from one language to another.
- Video – The Video SourceType returns a list of videos relevant to the query term.
- Web – The Web SourceType returns pages relevant to the queried term.
NUMBER_OF_RESULTS – The number of the search results to be returned.
OFFSET - The number of results from where the number of results will start counting.

We will use some of these types in our manage() function:

function manage($type){
 if($_GET['end']){
 $end= $_GET['end'];
 }else{
 $end=10;
 }
 if($_GET['start']){
 $start= $_GET['start'];
 }else{
 $start=0;
 }
 //Switch case on the type variable
 switch($type){
 case "web":
//if we search for web :
 $request ='http://api.search.live.net/json.aspx?Appid=28CDBBD47CD8F911BE7EA5C3CB748FE6EFA951FC&sources=web&Web.Count='.$end.'&Web.Offset='.$start.'&query=' . urlencode( $_GET["q"]);
 break;
 case "spell":
//Spell check
 $request ='http://api.search.live.net/json.aspx?AppId=28CDBBD47CD8F911BE7EA5C3CB748FE6EFA951FC&Query='.urlencode( $_GET["q"]).'&Sources=Spell&Version=2.0&Market=en-us&Options=EnableHighlighting';
 break;
 case "image":
//Search for images
 $request ='http://api.search.live.net/json.aspx?Appid=28CDBBD47CD8F911BE7EA5C3CB748FE6EFA951FC&sources=Image&Version=2.0&Image.Count='.$end.'&Image.Offset='.$start.'&query=' . urlencode( $_GET["q"]);
 break;
 case "video":
//Video search
 $request ='http://api.search.live.net/json.aspx?Appid=28CDBBD47CD8F911BE7EA5C3CB748FE6EFA951FC&sources=Video&Version=2.0&Video.Count='.$end.'&Video.Offset='.$start.'&query=' . urlencode( $_GET["q"]);
 break;
 case "phonebook":
//phonebook service
 $request ='http://api.search.live.net/json.aspx?Appid=28CDBBD47CD8F911BE7EA5C3CB748FE6EFA951FC&sources=Phonebook&Version=2.0&Market=en-us&UILanguage=en&Latitude=47.603450&Longitude=-122.329696&Radius=100.0&Phonebook.FileType=YP&Options=EnableHighlighting&Phonebook.Count='.$end.'&Phonebook.Offset='.$start.'&query=' . urlencode( $_GET["q"]);
 break;
 case "translate":
//translate service. This one will translate the term to Greek
 $request = 'http://api.search.live.net/json.aspx?AppId=28CDBBD47CD8F911BE7EA5C3CB748FE6EFA951FC&Query=' . urlencode( $_GET["q"]).'&Sources=Translation&Version=2.2&Market=en-us&Options=EnableHighlighting&Translation.SourceLanguage=en&Translation.TargetLanguage=el';
 break;
 case "answers":
//Answers service.
 $request = "http://api.search.live.net/json.aspx?AppId=28CDBBD47CD8F911BE7EA5C3CB748FE6EFA951FC&Query=".urlencode( $_GET["q"])."&Sources=InstantAnswer&Version=2.0&Market=en-us";
 break;
 }
//we get the contents of the file
 $response = file_get_contents($request);
//and we decode the json data
 $jsonobj = json_decode($response);
//Return the decoded object
 return $jsonobj;
}

The next thing to do is to check if there is a request:

if($_GET['q']){
 $obj = manage($_GET['type']);
}

and then we display the results using a switch case on the type:

switch($_GET['type']){
 case "web":
 ?>
 
 SearchResponse->Web->Results as $value){
 ?>
 Title; ?>
Description); ?>
DisplayUrl; ?>
 
 
 
 
 
 SearchResponse->Image->Results as $value){
 ?>
 Thumbnail->Url;?>" alt="Title); ?>">
 
 
 
 
 SearchResponse->Video->Results as $value){
 ?>
 StaticThumbnail->Url;?>" alt="Title); ?>">
 
 
 
 
 SearchResponse->Phonebook->Results as $value){
 ?>
 Title; ?>
 
Business); ?>
 Phone: PhoneNumber; ?>
 Address: Address; ?>
 City: City; ?>
 
 
 
 Translated to Greek:".$obj->SearchResponse->Translation->Results[0]->TranslatedTerm."";
 break;
 case "spell":
 echo "Spelled like this:
".$obj->SearchResponse->Spell->Results[0]->Value."";
 break;
 case "answers":
 echo "Your Answer is:
".$obj->SearchResponse->InstantAnswer->Results[0]->InstantAnswerSpecificData->Encarta->Value."";
 break;
}
?>


 
 
 0){
 ?>
 Less
 
 
 
 More

The last lines will display a simple pager.

The Full PHP code

This is the code we used for our example:


 
 SearchResponse->Web->Results as $value){
 ?>
 Title; ?>
Description); ?>
DisplayUrl; ?>
 
 
 
 
 
 SearchResponse->Image->Results as $value){
 ?>
 Thumbnail->Url;?>" alt="Title); ?>">
 
 
 
 
 SearchResponse->Video->Results as $value){
 ?>
 StaticThumbnail->Url;?>" alt="Title); ?>">
 
 
 
 
 SearchResponse->Phonebook->Results as $value){
 ?>
 Title; ?>
 
Business); ?>
 Phone: PhoneNumber; ?>
 Address: Address; ?>
 City: City; ?>
 
 
 
 Translated to Greek:".$obj->SearchResponse->Translation->Results[0]->TranslatedTerm."";
 break;
 case "spell":
 echo "Spelled like this:
".$obj->SearchResponse->Spell->Results[0]->Value."";
 break;
 case "answers":
 echo "Your Answer is:
".$obj->SearchResponse->InstantAnswer->Results[0]->InstantAnswerSpecificData->Encarta->Value."";
 break;
}
?>

The API key displayed above is a fictional key. You should get one from Bing in order to use the API. Get one now! It is free.

Here is a live example of the application described above. We called it GooBingoo!, but Bingoo! might have been a better name for it ;)

Learn Programming With Youtube

CAPTCHA Problems, A Suggestion and Alternatives

Kerasiotis Vasileios — Tue, 29 Sep 2009 16:48:20 +0000

You have your blog ,contact form, application setup and your content is dominating the search engines. You get tons of traffic every day and tons of spam also. Spam about everything you can imagine: pills, drugs and links to casinos. Even the president of the united states came to your blog and commented on one of your posts asking you to buy something… What can you do to stop this?

CAPTCHA

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a way to stop computers from posting forms. A form can be a contact form, a comment form or anything that can be posted to the backend of a web application. There are numerous types of CAPTCHAs. We all have been asked to fill in a word that is displayed as an image during our surfing and some of us use them to one of our sites.

The most known CAPTCHA type is an image displaying a word which is distorted in some way. So we find CAPTCHAs like the one used on Yahoo!:

This type of CAPTCHA is used by Yahoo!

or like the ones previously used by Rapidshare:

Used by Rapidshare in the past

or a typical CAPTCHA with lines obscuring the words:

Another type of an image CAPTCHA

There are some other CAPTCHA types that you should be aware of. For example asking the person to type in the sum of two numbers like this one:

Please add 6 plus 2 and fill in the result

This is something most of computers can’t figure out especially if it is displayed in an image like this one:

Obscured numbers addition

but it is not bulletproof because a bot can be configured to read the numbers and add them. Another nice but still not bulletproof CAPTCHA style is the one used in some sites that ask the visitor to write the a word backwards. So it looks like this:

Please write the word “double” backwards

Still not quite secure, because someone could grab the word surrounded by “quotes” and reverse it. It is pretty simple to do it.

So we see that there are a lot of options that really don’t give any solution. You might think that the CAPTCHA used by Rapidshare is pretty strong and it would help against spam, but it is not user friendly at all. You don’t want your visitors to get headaches trying to solve your little enigma there. You want to keep bots away.

Another problem when using captchas is usability. What will happen if a visually impaired person visits your site with a screen reader? You need a sollution that can handle this usability feature too. Javascript is also not so usable because a lot of screen readers don’t support it.

No Solution!!! What can i do?

Before we suggest our idea, we should first try to explain why most of the CAPTCHA types mentioned above. Having a smooth distorted word in an image is very easy for a program to scan it and read the characters while having an image with very distorted text might make your visitors go away. On the other hand, having a sentence asking someone to write a word or add some numbers is very user friendly but bot friendly too. If i was a spammer i would look for patterns in the sentence and configure my bot to bypass the test.

A suggestion

We need a test that will be strong and user friendly too. So we recommend a solution that will be text based but it will alter it’s pattern so that it will be harder to bypass it. The solution that we suggest is very easy to implement. We will use PHP for this one. First we need to create some arrays:

//vowels array
 $vowels = array('a','e','i','o','u','y');
 //consonants array
 $consonants = array('b','c','d','f','g','j','k','l','m','n','p','q','r','s','t','v','w','x','z');
 //words array
 $words = array('design','develop','program','tools','awesome','stunning','person','computer','jeez','smashing','source','distorted','example','lorem','ipsum');
 //Patterns
 $patterns = array('vowelsout','consout','backwards','firstlast');

The arrays above will be used to alter the pattern each time we load a new test for the user. So we see that we have 4 different patterns to choose from:

vowelsout – This will strip all vowels from the word
consout – This will do the opposite of vowelsout
backwards – This will reverse the word
firstlast – This will ask the user to fill in the first and the last char of the word

The full code is:

session_start();

function captcha(){
 //vowels array
 $vowels = array('a','e','i','o','u','y');
 //consonants array
 $consonants = array('b','c','d','f','g','j','k','l','m','n','p','q','r','s','t','v','w','x','z');
 //words array
 $words = array('design','develop','program','tools','awesome','stunning','person','computer','jeez','smashing','source','distorted','example','lorem','ipsum');
 //Patterns
 $patterns = array('vowelsout','consout','backwards','firstlast');

 //first we need to decide what pattern to use. So we pick one randomly
 $pattern = $patterns[array_rand($patterns, 1)];
 //then we pick a random word from the words array
 $word = $words[array_rand($words)];
 //then we check what the pattern is and we go on using this technic
 switch($pattern){
 case"vowelsout":
 //This pattern strips vowels from the word
 $_SESSION['CAPTCHA'] = str_replace($vowels,"",$word);
 //a string to display to the visitor:
 $question = "Please write the word '$word' without vowels";
 break;
 case"consout":
 //This is the opposite of the vowelsout pattern
 $_SESSION['CAPTCHA'] = str_replace($consonants,"",$word);
 //a string to display to the visitor:
 $question = "Please write the word '$word' without consonants";
 break;
 case"backwards":
 //This one reverses the word
 $_SESSION['CAPTCHA'] = strrev($word);
 //a string to display to the visitor:
 $question = "Please write the word '$word' backwards";
 break;
 case"firstlast":
 //This one takes the first and the last char of the word
 $_SESSION['CAPTCHA'] = $word[0].$word[strlen($word)];
 //a string to display to the visitor:
 $question = "Please write the first and the last characters of the word : '$word'";
 break;
 }
 echo $question;
}

captcha();

We can add more patterns to our CAPTCHA system and each time the code the user needs to write, is stored in a session variable that can be used later to test if the user posted the right code. You can make some more improvements to the patterns. For example you can replace all vowels with a number and ask the user something like this:

Please replace the vowels from this word: ‘awesome’ with number 1 (Sollution: 1w1s1m1)

Honeypots

A honeypot is a trap we set to bots in order to detect if an action was generated by a human or a computer. Generally, spam bots check for standard form fields to fill. Some of these fields include:

Name
Username
Email
Surname
Body
Message

So a honeypot would be a form that has one or all of the above fields but does not need the user to fill in something. In fact, a honeypot would refuse to accept a form that has one of these fields filled with data. The implementation is plain easy. You set one or more honeypot fields in a form and you use CSS to hide them from the user (Bots do not understand CSS). When the form is submitted, you check if the field(s) are empty and if not, you refuse to accept the form contents.

Dynamic Creation of Form Fields Names

Another cool and strong form protection against spam bots can be achieved by creating form field names in a dynamic way. You create a hash for each field with some random salt and you store this hash in a session variable. When the bot comes to your page, it does not know what to do and where. Even if the spammer configures the bot to assign email to a given field, there is no chance (less than 1%) that the same field name will ever exist. So the bot is lost.

Some CAPTCHA implementations

During our research for CAPTCHA systems we run across some interesting implementations. These are:

Ajax Fancy Captcha

This one asks you to drag and drop a specified item into a circle. Clever implementation because bots don’t support javascript. Do they.

Captcha that wants you to know somethings

This one is a good solution for sites that need their visitors to have some knowledge of the topic they want to comment on. So for example on a topic about php, the question could be:

Which php function displays info about PHP? (Sollution: phpinfo)

Other

I read that somewhere on the net but i can’t remember where (Maybe Slashdot), that a solution to spam bots could be the use of flash animated text, easy for a human to read but hard for a bot to do the same.

In Vain

The most disappointing thing of all is human labor for spam purposes. A company can hire some hundreds of people that really need the money to solve CAPTCHAs and all your tests to be useless. Some other spam technics include the use of sites that ask from visitors to solve captchas in order to see nude images and many more mentioned on Wikipedia that are worth reading.

Introducing Qool CMS. A New Open Source CMS

Kerasiotis Vasileios — Mon, 28 Sep 2009 16:25:16 +0000

We are happy to announce to all of our visitors and to the Open Source community that our own propriarity CMS, Qool, is now available as Open Source software. We wanted to give Qool, the opportunity to evolve and become a new sollution and addition to the world of CMSes. You can grub it’s source code here. The package is GPL licenced.

Update: The project is hosted on Sourceforge too. Anyone interested can opt in for membership.

What is Qool

Qool is a content management system (framework) that is greatly inspired by Joomla and Wordpress. It is extendable and fast. It is completely modular and nearly all functionality can be substituted with ease.

Built-in Tools

We have added some extra functionality in Qool’s core.The admin module is one of the 3 pre-installed modules (the others are the user manager module and the system module) and has built in features like:

Image Editor
Archive Editor
Text Editors
Rich Text Editor
Language Editing
Reading of Microsoft Excel files

Analysis of Qool Features

Multisite creation

Qool supports a Wordpressμ like functionality allowing you to create and manage multiple sites running on the same package. So you can create unlimited sites with just one Qool installation.

Comment Support on Everything

The commenting system can be used to comment all modules and module items on the Qool cms. Each module can be configured to support commenting or not.

Publish Content in Various Formats

Qool can export content in various formats like:

PDF
XML
RTF
Open Document Text
Printer Friendly Format

Modules Support Multisites too

Each module runs the same way Qool does. So you can use the same module for any site, without the need of seperate folders and directories and not mess each other around. Modules can use their own blocks.

Wordpress Plugins Support (Experimental)

Qool is able to run some Wordpress plugins too. Most of filter type plugins can be run in Qool too. For example the share buttons plugin for WP

SEF URLs

Qool CMS supports SEF URLs by default. A typical Qool URL looks like: www.example.com/articles/article-title.htm

Templates

Not only Qool has it’s own template system based on Smarty, but it also supports Wordpress, Xoops and Drupal themes with little or no modifications. Some examples of this functionality :

Qool Running with the Wordpress Pixel Theme
Qool Running with the Green Drupal Theme
Qool Running with the EADJ2.1 Xoops Theme

Localization

Qool takes into consideration user locales. It can also be translated to any language using the builtin language files editor.

Easy and Safe module setup

Installing and removing modules is plain easy. Everything is controlled from the Qool system and if a module fails to install, the process rolls back and everything is like before.

Internal Recycle Bin

You can delete and restore nearly anything. From articles to users and comments, Qool CMS treats everything as content that can be managed.

SQL abstraction layer

The CMS uses the PEAR DB package to support other databases than MySQL. MySQL is officialy supported but the community can use the layer to add support for other DBs too.

Qool CMS also supports and has functionality for:

Content Approval
Pagers
Macro Language
Email Posting
Image resizing
File searching
RPC
Shortcuts
Session Management
Caching
Zip, Rar, Tar Support
Email Client
Versioning
Workflow Engine
Sitemaps for Search Engines
Audit Trails
FTP Support
File Manager
Antiflood mechanism

We make a call to the Open Source community to help us improve Qool CMS. We know that the code can be better, more secure, and faster. We want to make this cms the bridge of features from popular CMS’s like Wordpress, Xoops, Drupal and Joomla and leave out all the not needed functionality.

API Documentation and Qool Manual

The manual(not complete) and some api documentation can be found online and is also included in the Qool Package bellow.

Download

You can download Qool CMS from Sourceforge

Web 3.0 Will Be All About Web Services. Learn The Basics

Kerasiotis Vasileios — Sat, 26 Sep 2009 17:23:59 +0000

The web has evolved in many ways. From the static html web to the dynamic pages and from the publisher’s content to the user created content (web 2), the web has gone through many stages. As mentioned at the Service Web 3.0 project, the next web stage will be web services driven. We will be able to connect any device with the internet and manage this device remotely.

So, if web services is the future, you should be able to create and use them so that it will be easier for you to follow the evolution it will bring. We will try to give you some info about web services using SOAP. How to create a service, how to use it from a web based or a desktop application and some known web services that might come handy.

The Tools

We will be using some tools. The first tool we need to have is soapUI.

soapUI is a free and open source desktop application for

inspecting Web Services
invoking Web Services
developing Web Services
Web Services Simulation and Mocking
Functional, Load and Compliance testing of Web Services

It is mainly aimed at developers and testers providing or consuming WSDL or REST based Web Services (Java, .net, etc). Functional and Load Testing can be done both interactively in soapUI or within an automated build or integration process using the soapUI command line tools.
Mock Web Services can easily be created for any WSDL and hosted from within soapUI or using the command-line MockService runner. IDE-plugins are available for

eclipse plug in
IntelliJ IDEA plug in
NetBeans plug in

soapUI requires Java 1.5 and is licensed under the LGPL license.

We will also need a PHP library that will make our life easier. We will be using NuSOAP for this. NuSOAP is a rewrite of SOAPx4, provided by NuSphere and Dietrich Ayala. It is a set of PHP classes – no PHP extensions required – that allow developers to create and consume web services based on SOAP 1.1, WSDL 1.1 and HTTP 1.0/1.1.

And last but not least, Microsoft Visual C++ Express Edition in order to create our desktop client. You might also need to get a smilies pack, if you don’t have one.

The Challenge

We need a web service that will accept simple text as argument and it will return an image url depending on the command given. Some of you might have guessed that this service is a smilies web service :)

The Database Structure

We need only one table for this service. Create a new database named servesmiles and add a new table named smilies.

Table smilies:

CREATE TABLE IF NOT EXISTS `smilies` (
 `id` int(11) NOT NULL auto_increment,
 `image` varchar(250) collate utf8_unicode_ci NOT NULL,
 `code` varchar(50) collate utf8_unicode_ci NOT NULL,
 PRIMARY KEY  (`id`),
 KEY `code` (`code`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1 ;

The Directory Structure

Create a directory named smileserv and 1 subfolder named smilies and place your smilies in it. We will also place the NuSOAP library in a folder named nusoap. There are 2 files we need to create too. The first one named server.php and the second one named index.php :

The Service

The service is a simple function that will query the database and return the smilie path. We don’t include a password cause we test it local. You might need a password if you use it online.

function getSmilie($text){
 //connect to the database
 $conn = new PDO('mysql:host=localhost;dbname=servesmiles', 'root', '');
 //setup the sql statement
 $sql = "SELECT * FROM `smilies` WHERE `code`=?";
 $data = array($text);
 //prepare
 $sth = $conn->prepare($sql);
 //execute
 $sth->execute($data);
 //return the image
 $result = $sth->fetch();
 return $result['image'];
}

So, our function will look into the database table for the image code provided and it will return the smilie image path. Next thing to do is to create the web service server file.

The Server

Creating a server is very easy using the NuSOAP library. All you have to do is to include the nusoap library and register the methods you will use:

// load SOAP library
require_once("./nusoap/nusoap.php");
// load library that holds implementations of functions we're making available to the web service

// set namespace
$ns="http://localhost";
// create SOAP server object
$server = new soap_server();
$server->soap_defencoding = "utf-8";
$server->decode_utf8 = false;
// setup WSDL file, a WSDL file can contain multiple services
$server->configureWSDL('JeezApi',$ns);
$server->wsdl->schemaTargetNamespace=$ns;
// register a web service method
$server->register('smileme',
 array('smilecode' => 'xsd:string'),     // input parameters
 array('smilepath' => 'xsd:string'),     // output parameter
 $ns
 );

function smileme($smilecode){
 //include the service file
 include "./index.php";
 return new soapval('smilepath','xsd:string',getSmilie($smilecode));

}// service the methods
$server->service($HTTP_RAW_POST_DATA);

Now we are almost ready. You can check what your server.php file does by opening it in your browser:

http://localhost/smileserv/server.php:

http://localhost/smileserv/server.php?wsdl :

So, we created a web service server with less than 27 lines of code, using the NuSOAP library.

Testing the Service

We need to test the service. This is where soapUI comes into play. Load soapUI and create a new project:

Make sure you fill in the correct WSDL URI and press the OK button.

If everything is ok, you should see something like this:

Now, if you double click on the Request 1 option, a new window will open that looks like this:

Try clicking the green arrow on top left of this window. You will notice that you get an empty response. This is because there are no data in our database table. Try inserting an image name and a code in the smilies table. For the example bellow we will use “:P” as a smilie code that will point to the tongue.gif file (you can find it in the smilies package provided above):

INSERT INTO `servesmiles`.`smilies` (
`id` ,
`image` ,
`code`
)
VALUES (
NULL , 'tongue.gif', ':P'
);

Now lets try our service. Load the Request 1 option from soapUI and replace the “?” with “:P”. Press the green arrow button on the top left and the window will look like this:

This means that our service works as it should. Now we should see how we can use the service from another site using PHP.

A PHP Client

Creating a client for the service is even easier. The way to go is similar to the server creation process. You include the NuSOAP library and create a new client object.

File client.php:

//include the nusoap library
include './nusoap/nusoap.php';
//set the wsdl file src
$wsdl="http://localhost/smileserv/server.php?wsdl";
//and create a client
$c=new nusoap_client($wsdl,'wsdl');
$t=array('smilecode'=>':P');
//then call the method smileme
$file = $c->call('smileme', $t);
//and echo the image
echo "";

You can now try the client. Point your browser to the client.php file and you will be able to see the tongue.gif file

A C++ Client

We will create a C++ client using Microsoft Visual C++ Express edition. Create a windows forms project with 1 textbox 1 button and a webbrowser control:

Next, add a new web reference to your project:

Fill in the url to the server.php file. Don’t forget to add the wsdl parameter:

Now double click the “Hit me!” button and put this code in the button1_Click method:

localhost::JeezApi^ proxy =
 gcnew localhost::JeezApi();
 this->webBrowser1->Navigate(System::String::Concat("http://localhost/smileserv/smilies/",proxy->smileme(this->textBox1->Text)));

Thats it! Now Run your client and fill in the “:P” code we set in the database:

I hope this tutorial was fun to read (:

Some Known Web Services

Yahoo! offers some great web services. You can use the Yahoo! network to create your own search engine, spell checkers and many more. Microsoft also offers Bing services and Google does also. Nearly all known networks (facebook, Twitter, Flickr etc) provide web services.

You can also find interesting web services with the seekda web services directory. For example the Excel web service.
