history of php

•   PHP development began in 1994 when the developer Rasmus Lerdorf wrote a series of Common Gateway Interface (CGI) Perl scripts, which he used to maintain his personal homepage. The tools performed tasks such as displaying his resume and recording his web traffic. He rewrote these scripts in C for performance reasons, extending them to add the ability to work with web forms and to communicate with databases and called this implementation "Personal Home Page/Forms Interpreter" or PHP/FI. PHP/FI could be used to build simple, dynamic web applications.


•     Officially PHP/FI 1 released in 8 JUNE 1995.


•     A development team began to form and, after months of work and beta testing, officially released PHP/FI 2 in November 1997.


•     Zeev Suraski and Andi Gutmans released a stable version name to the recursive acronym PHP: Hypertext Preprocessor.[3] Afterward, public testing of PHP 3 began, and the official launch came in June 1998.


•     PHP 4 released On May 22, 2000, powered by the Zend Engine 1.0, was released.


•     PHP 5 was released, powered by the new Zend Engine II in July 13, 2004.PHP 5 included new features such as improved support for object-oriented programming, the PHP Data Objects (PDO) extension (which defines a lightweight and consistent interface for accessing databases), and numerous performance enhancements.


•     In 2008 PHP 5 became the only stable version under development. Late static binding had been missing from PHP and was added in version 5.3.


•     A new major version has been under development alongside PHP 5 for several years. This version was originally planned to be released as PHP 6 as a result of its significant changes, which included plans for full Unicode support.
