hi,
As we are all knowing that PHP is creating innovation in the web development in every release.

Here the History of PHP is summarized


PHP was written as a set of CGI binaries in the C programming language by the Danish/Greenlandic programmer Rasmus Lerdorf in 1994, to replace a small set of Perl scripts he had been using to maintain his personal homepage.Lerdorf initially created PHP to display his résumé and to collect certain data, such as how much traffic his page was receiving. Personal Home Page Tools was publicly released on 8 June 1995 after Lerdorf combined it with his own Form Interpreter to create PHP/FI (this release is considered PHP version 2).
Zeev Suraski and Andi Gutmans, two Israeli developers at the Technion IIT, rewrote the parser in 1997 and formed the base of PHP 3, changing the language's name to the recursive initialism PHP: Hypertext Preprocessor. The development team officially released PHP/FI 2 in November 1997 after months of beta testing. Public testing of PHP 3 began and the official launch came in June 1998. Suraski and Gutmans then started a new rewrite of PHP's core, producing the Zend Engine in 1999.They also founded Zend Technologies in Ramat Gan, Israel, which actively manages the development of PHP.
In May 2000, PHP 4, powered by the Zend Engine 1.0, was released. The most recent update released by The PHP Group, is for the older PHP version 4 code branch which, as of May 2007, is up to version 4.4.7. PHP 4 is currently still supported by security updates for those applications that require it.
On July 13, 2004, PHP 5 was released powered by the new Zend Engine II. PHP 5 included new features such as:
• Support for object-oriented programming
• The PHP Data Objects extension, which defines a lightweight and consistent interface for accessing databases
• Performance enhancements
• Better support for MySQL
• Embedded support for SQLite
• Integrated SOAP support
• Data iterators
• Error handling via exceptions
The latest stable version, PHP 5.2.3, was released on June 1, 2007.
