Zend Server Reference Manual
Zend Server is comprised of several components that each contributes important functionality to facilitate
the development process.
The components are:
Zend Debugger - The Zend Debugger communicates with the Zend (PHP) Engine to retrieve
runtime information and present it in Zend Studio for root cause analysis.
Zend Optimizer+ - The Zend Optimizer+ component speeds up PHP execution via opcode
caching and optimization.
Zend Guard Loader - The Zend Guard Loader is used in order to run PHP scripts that are
encoded with Zend Guard.
Zend Data Cache - The Zend Data Cache component provides a set of PHP functions to improve
performance, by storing data in the cache.
Zend Java Bridge- The Zend Java Bridge component makes it possible to use Java classes and
code from within PHP.
Zend Framework - An open source framework for developing Web applications and Web services
with PHP.
Zend Monitor - The Zend Monitor component is integrated into the runtime environment and
serves as an alerting and collection mechanism for early detection of PHP script problems.
Zend Page Cache - The Zend Page Cache component is used to cache the entire output of PHP
scripts, without changing the PHP code.
ZDS (Zend Download Server) - The ZDS (Zend Download Server) component improves Apache's
scalability by managing static content downloads and passing them to a dedicated process
optimized for parallel downloads (not supported in Microsoft Windows).
Zend Job Queue - The Jobs Component is used to streamline offline processing of PHP scripts.
Zend Code Tracing - Code Tracing enables real-time execution flow recording in Production
Environments.
