Zeev has been working for over five years on the PHP project. While working at the Web development department of Netvision, Israel's largest ISP, Zeev became acquainted with PHP/FI, and chose to use it in a Technion University Web project he was working on with fellow student Andi Gutmans. While working on the Web project, they stumbled over bugs and limitations in the PHP/FI 2.0 code. They decided to set aside their Web project (and their computer science studies) to redesign and rewrite the PHP language engine and some of the most popular PHP modules. Their efforts got the wheels turning for the creation of PHP 3.0. Zeev and Andi then went on to develop the Zend Engine -- the scripting language that powers PHP 4.0. They also designed other crucial PHP 4.0 components, such as a server abstraction layer and multi-threading support. Zeev is a graduate of the Technion - Israel Institute of Technology.
