CentOS Server Upgrade php5.1 to version 5.2 separately

Introduction: As Friends of the CentOS 5.5 system know, Yum has the default PHP version of php5.1, and if we want to use the latest stable version (php5.2.x series), we have to compile the installation.
Here's how you can use Yum to install the PHP version you need!
The following operations are performed at the terminal command line!
RPM--import Http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy
Wget-p/etc/yum.repos.d/http://repo.webtatic.com/yum/webtatic.repo
Yum--enablerepo=webtatic list php #发现有php5.2 and php5.3 can be upgraded
Yum--enablerepo=webtatic--exclude=php*5.3* list php #查看php5.2 packages
Yum--enablerepo=webtatic--exclude=php*5.3* update-y php #安装php5.2 version
Note: Option--exclude=php*5.3* #禁止升级为php5.3 version
