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.

上面的是说个人Zend 版本过低   

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

而后一路YES，OK和回车，中间须要添加apachectl目录之类的 根据提示填写，安装就完成。通常来讲，不须要另外编辑php.ini文件就能够正常工做了。

不过也能够去php.ini 里面看下  会出现下面的一些东西
