According to Lerdorf, he first started working on PHP in 1994 as a Personal Home Page Tool in order to to maintain his personal homepage and track the web-page traffic. He first released PHP/FI version 1.0′ on June 8, 1995. Lerdorf actively led the group developers Jim Winstead, Shane Caraveo, Stig Bakken, Andi Gutmans and Zeev Suraski in developing the next PHP versions and contributed to a number of other open source projects. Later, he wrote LIMIT clause to help the Apache HTTP Server and in 1995 it was added to the mySQL Database.
