安装phpMyAdmin 3.4.1，设置完毕后访问提示
PHP 5.2+ is required
#php -v
查出CentOS 5.6自带的php是5.1.6
两种解决方法：
1 使用低版本的phpmyadmin，下载phpMyAdmin-2.11.10-all-languages.tar.gz后再安装OK
2 升级php
升级方法一：
安装相应的GPG key
# rpm --import
新建一个repo
# /etc/yum.repos.d/utterramblings.repo
把以下内容添加进去，保存退出就OK了
[utterramblings]
name=Jason's Utter Ramblings Repo
baseurl=
enabled=1
gpgcheck=1
gpgkey=
#yum install php
安装出来的就是 php5.2.16
升级方法二：
#wget
#wget
#rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm
#vi /etc/yum.repos.d/remi.repo
#vi /etc/yum.repos.d/epel.repo
#vi /etc/yum.repos.d/epel-testing.repo
分别在这三个文件的最后，增加如下一行：
priority=1
#yum --enablerepo=remi update php
# php -v

PS:
当前安装时CentOS已经更新到5.3，所以实际下载的包可能有所不同：
wget
wget
rpm -Uvh remi-release-5-7.el5.remi.noarch.rpm epel-release-5-4.noarch.rpm
如果单独升级php将提示失败，只有联通mysql一起升级才可以，
所以我们必须执行以下命令才能升级php到5.2.9版本：
yum –-enablerepo=remi update php* mysql*
提示："缺少mysqli扩展""缺少mcrypt扩展" 解决方式：
[root@www libraries]# yum --enablerepo=remi update php-mysqli
