PHP之常用操作

　　在最高权限下执行相关命令

　　1)查看PHP配置

php --ini
Configuration File (php.ini) Path: /www/server/php//etc
Loaded Configuration File:         /www/server/php//etc/php.ini
Scan for additional .ini files in: (none)
Additional .ini files parsed:      (none)

　　2)重启服务

service php-fpm restart

Redirecting to /bin/systemctl restart  php-fpm.service

　　3) 隐藏请求response 返回的  X-Powered-By:PHP/7.0.25

修改php.ini配置文件

; 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.
; http://php.net/expose-php
expose_php = On

将On 改成Off  即可

　　常见错误:

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

　　　　将php.ini中disable_function 中将  proc_open、proc_get_status 去除并重启PHP
