There are other server-side languages such as Java Server Page (JSP), ASP.NET just to mention a few but PHP is about the most popular having been installed in over 20 million domains.PHP was created sometime in 1994 by Rasmus Lerdorf. During mid 1997, PHP development entered the hands of other contributors. Two of them, Zeev Suraski and Andi Gutmans, rewrote the parser from scratch to create PHP version 3 (PHP3).

It was a set of PERL scripts are made to create a dynamic web page. Then in 1996 he released PHP version 2.0 which has the ability to access database and can be integrated with HTML. In 1998, exactly on the date of June 6, 1998 out of PHP version 3.0 released by Rasmus himself with a group of software developers .. The latest version, PHP 4.0 is out on May 22, 2000 is a more complete version than the previous version. The most fundamental change in PHP 4.0 is an integrated Zend Engine created by Zend Suraski and Andi Gutmans who is a refinement of PHP scripting engine.
