PHP Zend Optimization

For many generic programming languages, efficiency of applications depends also on compiler used to compile application. But PHP is a general-purpose scripting language. It means PHP code is processed by an interpreter application. So is it still possible to optimize PHP applications performance on a "compilation" level? Well yes it is.

Zend Technologies provides a free runtime application - "Zend Optimizer", which improves performance by scanning PHP's intermediate code and passing it through multiple Optimization Passes to replace inefficient code patterns with more efficient code blocks. The replaced code blocks perform exactly the same operations as the original code, only faster.

You can use phpinfo() function to check if "Zend Optimizer" is already installed on your computer, by searching for Zend Optimizer keywords in paragraph with "This program makes use of the".

Or you can download and install it free of charge from official Zend Technologies website
