Summary  : PHP scripting language for creating dynamic web sites 
URL   : http://www.php.net/ 
License  : PHP and Zend and BSD 
Description : PHP is an HTML-embedded scripting language. PHP attempts to make 
      : it easy for developers to write dynamically generated web pages. 
      : PHP also offers built-in database integration for several 
      : commercial and non-commercial database management systems, so 
      : writing a database-enabled webpage with PHP is fairly simple. The 
      : most common use of PHP coding is probably as a replacement for CGI 
      : scripts. 
      : 
      : The php package contains the module (often referred to as mod_php) 
      : which adds support for the PHP language to Apache HTTP Server.

我的phpinfo没有列出OPcache。它也不在我的php.ini文件中。

我该如何启用它？
