默认上expose_php默认是开的。关闭“expose_php”参数可以使php隐藏它的版本信息。
[root@centos66 ~]# vi /etc/php.ini
在你的php.ini, 定位到含有expose_php的那行把On设成Off:
expose_php = Off
在此之前,web服务器头看上去就像这样:
[root@centos66 ~]# curl -I http://www.ehowstuff.com/
HTTP/1.1 200 OK Server: nginx Content-Type: text/html; charset=UTF-8 Vary: Accept-Encoding X-Powered-By: PHP/5.3.3 X-Pingback: http://www.ehowstuff.com/xmlrpc.php Date: Wed, 11 Feb 2015 14:10:43 GMT X-Page-Speed: 1.9.32.2-4321 Cache-Control: max-age=0, no-cache
更改并重启 Web 服务后,php就不会在web服务头中显示版本了:
HTTP/1.1 200 OK Server: nginx Date: Wed, 11 Feb 2015 15:38:14 GMT Content-Type: text/html; charset=UTF-8 Vary: Accept-Encoding X-Pingback: http://www.ehowstuff.com/xmlrpc.php Date: Wed, 11 Feb 2015 14:10:43 GMT X-Page-Speed: 1.9.32.2-4321 Cache-Control: max-age=0, no-cache
