What is the Zend Optimizer?

The Zend Optimizer is one of the most popular PHP plugins for performance-improvent, and has been freely available since the early days of PHP 4. It improves performance by taking PHP's intermediate code through multiple Optimization Passes, which replace inefficient code patterns with efficient code blocks. The replacement code blocks perform exactly the same operations as the original code, only faster.

In addition to performance-improvement, the Zend Optimizer also enables PHP to transparently load files encoded by the Zend Encoder or Zend SafeGuard Suite.

The Zend Optimizer is a freely-available product from   Zend Technologies. Zend Technologies is the company that develops the scripting engine of PHP, also known as the   Zend Engine.

上面的是說個人Zend 版本過低   

wget http://www.CTOHome.com/linux-vps-pack/zend.sh;sh ./zend.sh;

而後一路YES，OK和回車，中間須要添加apachectl目錄之類的 根據提示填寫，安裝就完成。通常來講，不須要另外編輯php.ini文件就能夠正常工做了。

不過也能夠去php.ini 裏面看下  會出現下面的一些東西   

#[Zend]

#zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.3

#zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.3
