我安装了PHP 5.3.3的Centos 6.5。 我从PHP 5.3.3升级到PHP 5.4成功。在命令行上显示：
[root@localhost ~]# php -v
PHP 5.4.16 (cli) (built: Nov 19 2014 08:05:17)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies
但是，当我在网上回应phpinfo时，它显示： PHP版本5.3.3
我需要使用PHP 5.4。我该怎么办？
运行grep：
之后的结果[root@localhost ~]# yum list installed | grep php
