Run PHP Web Applications on the Java Platform

There has been a lot of commotion and even a book with having Ruby on Rails run on the Java VM. But looking past the JRuby hype it is clear that PHP has a several orders of magnitude more open source code, projects, and corporate backing than Ruby on Rails. The folks behind the Resin application server have the ubiquitous of PHP and have developed Quercus, a PHP 5 implementation written in Java.

Quercus is available with the latest Resin but it is also available for download as a WAR file which can be deployed on Resin or other application Servers such as GlassFish.
Getting Started

Get the latest version of Resin server, as of this writing the latest version is Resin 3.1.3. To start the server just run the \bin\httpd script from the command prompt. If you look around the Resin install directory you will find a php folder where the Quercus WAR file is already configured to handle any PHP file. To give the Quercus PHP engine a try, lets create a simple test. First lets create phptest directory in \webapps. In the phptest directory create a new file, index.php, and add the following text to it.

The phpinfo method outputs a large amount of PHP configuration information. I usually print this information out to ensure that PHP is setup correctly. If you have already started the Resin server you can direct your browser to the following URL: http://localhost:8080/phptest/

You should be looking at a screen that looks like the following screen shot.

Mixing PHP with Java

Since Quercus is written in Java there are hooks to import and mix Java classes in your PHP files. Lets import a Java class and manipulate it in PHP. In the next sample piece of code I will import a Java HashMap class and manipulated it PHP. The import functionality is obviously not part of PHP but an extension made possible by Quercus. .

put(‘california’, 1000);
$map->put(‘oregon’, 1200);

$total = 0;
// Iterate over keys and sum values
for($itr = $map->keySet()->iterator(); $itr->hasNext(); ) {
$key = $itr->next();
$total += $map->get($key);
print “Total $total”;


Once a Java class has been loaded it can be handled just like any other object in PHP. In addition having access to JDK classes, you can import your own Java code. You can import any class that is available in your web applications class loader.
Run PHP Applications

Using Quercus and Resin you can deploy full fledge PHP web applications such as WordPress or Joomla! To get a PHP application running on Resin with Quercus you just need to unzip the application into the \webapps directory. Since your PHP application would be running on top of Java you need to have the right JDBC dirver installed in the \lib directory. This is usually all you have to do to have a PHP application to run on JSP/Servlet container like Resin.

There is a list of PHP applications that are known to be running on Java via Quercus.

Quercus opens a lot of opportunities for PHP web development. Now you don’t really have to choose between languages or frameworks, develop in what you know is best for the task and resources at hand and interoperate between PHP, Java, Ruby, Groovy whatever not at the XML level but at the bytecode.




How to refresh DIV using jquery

There are very simple steps to achieve this:
Step 1:
Copy the following code and paste it in the head section of your webpage.

<script src="
var auto_refresh = setInterval(
}, 20000);

Here , above the file “reload.php” will be reloaded in every 20000ms ie 20 second . You can change the file which you have to reload and you can also change the reload time as per your requirement.
and secondly , the #loaddiv is the name of DIV which is going to be refreshed.

Step 2:
and now you need to put the div in the body section of your page

<div id="loaddiv"> 

Step 3:
Now finally you need to write the code for the file “reload.php” which will extract the contends from the other page or it also may contain the code to read the data from the database depending upon requirement.
here i am going to read a small content from another site. you can copy , paste the code and save it as the filename “reload.php”. in the same folder that contains the source code.

echo"this auto loaded content ";

Now your page is ready .

Display a Success Message like Twitter



i find the Css and Jquery way to display the Error or Success Message Like Twitter. For this you need Jquery.js and the Small css


Here Is my Code




text-align: center;
display: none;
width: 100%;
position: fixed;
padding-top: 8px;
padding-bottom: 8px;
margin: 0;
font-weight: bold;
font-size: 1.2em;
overflow: visible;
.success {background:#FFF;color:#264409;border-color:#c6d880;}
.error, .alert, .notice, .success, .info {padding:0.8em;margin-bottom:1em;border:2px solid #ddd;}
.error, .alert {background:#fbe3e4;color:#8a1f11;border-color:#fbc2c4;}



var notifyCallBack;

function showNotification(message, type, callback) {

notifyCallBack = callback;

var notification = $(“#notification”);
notification.removeClass(“success notice error”);

//Make sure it’s visible even when top of the page not visible
notification.css(“top”, $(window).scrollTop());
notification.css(“width”, $(document).width()/2 +40);

// $(“#notification-text”).html(message);

//show the notification
notification.slideDown(“slow”, function() {


function hideNotification() {
$(“#notification”).slideUp(“slow”, function() {
if (null != notifyCallBack && (typeof notifyCallBack == “function”)) {
//reset the callback variable
notifyCallBack = null


In Html


Past the Below code


<div id=”notification” class=’notification’>

<span id=’notification-text’></span>



call the function Body on load or at the end of the page showNotification(”, “success”, function(){});




Convert XML to JSON in PHP

IBM’s developerWorks has posted an interesting article on converting XML to JSON using PHP. At first glance, the question would be “Why”? After all, both XML and JSON serve similar purposes and they both do their job. Almost. It turns out that people find it much easier to process JSON data in the browser than XML. Since many web services return XML, there needs to be a conversion process. Here’s where IBM’s article comes in. Here’s a quote where they talk a little about what they are trying to do.

More and more applications need to convert XML data into JSON. Several Web-based services are already popping up to do such conversions. The IBM T.J. Watson Research Center has developed a particular approach that uses PHP to do the conversion. This approach accepts XML string data as input and converts that into JSON-formatted data output. This PHP-based solution provides several benefits:

  • It can be run in a standalone mode, executed from the command line.
  • It can be included in an existing server-side code artifact.
  • It can be easily hosted as a Web service on the Web.

If you are working with web services, especially if you are proxying other’s services for your own use, you’ll want to read this article. It’s not a long read. If you are already familiar with XML and JSON then it’s even shorter because you can skip the “basics” sections. Most of the rest of the article is source code and explanations.

We used XML for the web service api, and converting xml(returned from REST web service API) to php array was consuming time, does using JSON for web service, increases the performance?

For this we need the xml2json.php
