Think Different

First you need to set your main domain to act as a catch-all subdomain. its like putting ServerAlias * so that each subdomain which is requested to the main domain reaches the same place. I mean if your main domain root is /home/admin/abc.com/htdocs/ then your catch-all setup shall send all sub-domain requests to that same directory /home/admin/abc.com/htdocs/ and then in the index.php file of this directory you can do this global $domainname; global $subdomainname; $domainarray = explode('.', $_SERVER['HTTP_HOST']); $index=count($domainarray)-1; $domainname= $domainarray[$index-1].".".$domainarray[$index]; $subdomainname=""; for($i=0;$i { if($subdomainname=="") { $subdomainname=$domainarray[$i]; } else { $subdomainname=$subdomainname.".".$domainarray[$i]; } } ShowCustomizedPageForsubdomain($subdomainname); ?> This function ShowCustomizedPageForsubdomain($subdomainname) can be easily implemented in two ways: 1) Either your stor...

New Functionality Support for PPP Exceptions Object Iteration Object Cloning Interfaces Autoload And much more, and it is faster too! The Basics The basic object operations have not changed since PHP 4. class my_obj { var $foo; function my_obj() { // constructor $this->foo = 123; } function static_method($a) { return urlencode($a); } } $a = new my_obj; // instantiate an object $a->my_obj(); // method calls my_obj::static_method(123); // static method call Similar, but not the same. While the syntax remains the same, internals are quite different.  Objects are now always being passed by reference, rather then by value. PHP 5 $a = new foo(); == PHP4 $a = &new foo(); While the old style constructors are supported, new more consistent mechanism is available. __construct() method. PPP Annoyance The VAR keyword for identifying class properties became deprecated and will throw an E_STRICT warning. PHP Strict Standards: var: Deprecated. Please ...

Introduction The "Hello, World" of the Google AJAX Language API The easiest way to start learning about this API is to see a simple example. The following example will detect the language of the given text and then translate it to English. html > head > script type = "text/javascript" src = "http://www.google.com/jsapi" > script > script type = "text/javascript" > google . load ( "language" , "1" ); function initialize () { var text = document . getElementById ( "text" ). innerHTML ; google . language . detect ( text , function ( result ) { if (! result . error && result . language ) { google . language . translate ( text , result . language , "en" , function ( result ) { var translated = document . getElementById ( "translation" ); if ( result . translation ) { translat...

The simplicity of scripting language PHP means it will be more popular than Java for building Web-based applications, Internet browser pioneer Marc Andreessen predicted Wednesday in a speech here at the Zend/PHP Conference. Java enjoyed great success when its inventor, Sun Microsystems, released it in 1995, largely because it was optimized better for programmers than for machines, making software development significantly easier, Andreessen said. Unfortunately, Java has acquired many of the unfavorable characteristics of its predecessors, he added. "Java is much more programmer-friendly than C or C++, or was for a few years there until they made just as complicated. It's become arguably even harder to learn than C++," Andreessen said. And the mantle of simplicity is being passed on: "PHP is such is an easier environment to develop in than Java." That opinion might not sit well with Java loyalists--and there are plenty of them among the millions of Ja...

While SQL-Injection is one of the most discussed security problems in web applications other possible problems for SQL queries like overlong input are usually ignored although they can lead to all kinds of security problems. This might be caused by the fact that security problems that are the result of overlong input are often buffer overflows and buffer overflows are something many web application security experts know nothing about and choose to ignore. There are however several security problems for SQL queries that are caused by overlong input and no one talks about. max_packet_size In MySQL there exists a configuration option called max_packet_size which is set to one megabyte by default and controls the maximum size of a packet sent between the SQL client and server. When queries or result rows do not fit into a single packet a error is raised. This means an overlong SQL query is never sent to the server and therefore never executed. This can lead to security problems when a...

MooCrop About MooCrop is an Image Cropping utility using the amazingly powerful mootools javascript framework. Alone it serves no practical purpose but used in conjuction with a server side script becomes a powerful image manipulation tool. Why Looking for a mootools solution, I searched and came up with a few existing implementations. Everything I came across were only partial implementations. Those that were more polished seemed to be sluggish and effecting the DOM needlessly in some places. I wanted a class that had a very intuitive interface and played nicely with the existing DOM and more importantly I wanted it to be fast. I came to the conclusion that developing my own would give me a better understanding of mootools and broaden my understanding of drag and drop inside the DOM. Initially I tried using the Drag.Base class found within mootools but found this to be clumbsy for this highly specialized form of dragging. With default options a single drag is mov...

If you want to use PHP in your company and your manager favours another solution, or if you are trying to convince a potential client that PHP really is a superior choice for the web, you are going to need to have a clear-cut set of reasons why you believe PHP is the superior language. This short list should help you get started: PHP is cross-platform. It can be run on Windows, Linux, BSD, Mac OS X, and Solaris, as well as a variety of other platforms. PHP is free. You can download the source code, use it, and even make changes to it without ever having to pay any licensing costs. You can even give away your own modified version of PHP. Note to critics: just because PHP is free, it does not mean you need to give your scripts away for free. PHP is fast. In the majority of scripts beyond basic benchmarks, PHP will easily compete with both Perl and Python, and usually pull ahead of Microsoft's ASP.NET by about 10-15%. Add to that the fact that PHP code can be cached for execution,...
