; Decides whether PHP may expose the fact that it is installed on the server
; (e.g. by adding its signature to the Web server header).  It is no security
; threat in any way, but it makes it possible to determine whether you use PHP
; on your server or not.

expose_php = On


将On 改成Off  即可

　　

　　4) 查看PHP扩展

php -m

 

 

 

 

　　常见错误:

　　　　1)  The Process class relies on proc_open, which is not available on your PHP installation.
