如何屏蔽掉 phpinfo() 函数

　　 
　　 在 php.ini 配置文件里面有这个选项

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.

写成
disble_functions = phpinfo
