Publisher review:Zend Engine is the centerpiece of PHP, and is the component that parses (in other words, 'understands') and executes all of your PHP files. The performance and reliability that the Zend Engine brought to PHP is the fuel that has made PHP the most popular language for dynamic web site development.
The Zend Engine is the centerpiece of PHP, and is the component that parses (in other words, 'understands') and executes all of your PHP files.
The Zend Engine is responsible for the following tasks in PHP:
- High performance parsing (including syntax checking), in-memory compilation and execution of PHP scripts
- Implementation of all of the standard data structures of PHP
- Interfacing with extension modules for connectivity to external resources and protocols, such as SQL, HTTP and FTP
- Overloading the Object Oriented syntax, for integration with Java and .NET
- Providing all of the standard services, including memory management, resource management and more for the whole of PHP
The Zend Engine was designed to be extensible, and allows extension modules such as debuggers, performance boosters and custom loaders to be dynamically integrated to it. Whenever you're using such a plug-in module, you're doing so thanks to the extensibility options of the Zend Engine!
