我们配置PHP环境的时候往往都会写PHPinfo（）；这个函数来测试PHP环境是否安装成功，但往往这个函数也会给系统带来安全隐患，那么如何让关掉这个函数呢？下面介绍一种方法：
修改PHP.ini文件，在里面找到如下行
， 代码如下:
disable_functions = ; This directive allows you to disable certain
; functions for security reasons. It receives
; a comma separated list of function names.
; This directive is *NOT* affected by whether
; Safe Mode is turned on or off.
; functions for security reasons. It receives
; a comma separated list of function names.
; This directive is *NOT* affected by whether
; Safe Mode is turned on or off.
将其写成
PHPinfo重启apache就能实现屏蔽PHPinfo（）；函数了。 原文链接：https://www.f2er.com/php/26430.html
