- Zend Engine
The Zend Engine is an
open source scripting engine (aVirtual Machine ), commonly known for the important role it plays in the web automation languagePHP . It was originally developed byAndi Gutmans andZeev Suraski while they were students at the Technion - Israel Institute of Technology. They later founded a company calledZend Technologies inRamat Gan ,Israel . The name Zend is a combination of their forenames, Zeev and Andi.The first version of the Zend Engine appeared in 1999 alongside PHP version 4. It was written as a highly optimized modular back-end, which for the first time could be used in applications outside of PHP. The performance, reliability and extensibility of the engine played a significant role in increasing the popularity of PHP.
The current version of the virtual machine is "The Zend Engine II" and is at the heart of PHP 5. The source code for the Zend Engine has been freely available under a BSD-style license since 2001; it is an open-source project, and there are now several programmers from all over the world who volunteer their time and skills to expand and improve the code base.
