本篇内容主要讲解“PHP怎么开启opcache提升代码性能”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“PHP怎么开启opcache提升代码性能”吧!
配置指令如下：
[opcache] zend_extension=opcache.so opcache.enable_cli=1 ;共享内存大小, 这个根据你们的需求可调 opcache.memory_consumption=256 ;interned string的内存大小, 也可调 opcache.interned_strings_buffer=8 ;最大缓存的文件数目 opcache.max_accelerated_files=4000 ;60s检查一次文件更新 opcache.revalidate_freq=60 ;打开快速关闭, 打开这个在PHP Request Shutdown的时候 会收内存的速度会提高 opcache.fast_shutdown=1 ;不保存文件/函数的注释 opcache.save_comments=0
实际性能对比：
下面是实际测试中没有开启opcache的数据：
