1- Remove older version of PHP 5.2.10.

• Detect if any PHP packages are installed.
• # yum list installed | grep php
• If packages are installed remove them.
• # yum remove php.x86_64 php-cli.x86_64 php-common.x86_64 php-gd.x86_64 php-ldap.x86_64 php-mbstring.x86_64 php-mcrypt.x86_64 php-mysql.x86_64 php-pdo.x86_64

2- Add PHP 5.4

• Add PHP 5.4 packages to yum using this command for CentOS 5.x.
• # rpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm
• Or CentOS 6.x
• # rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm

3- Check available PHP

• Now, you can check if the new PHP (5.4: php54w or 5.5: php55w) packages are available: 
• # yum list available | grep php
• Or version specific search
• # yum list available | grep php54

4- Install new PHP

• Next, install the new PHP 5.4 or 5.5 packages, for example when installing PHP 5.4 packages I used: 
• # yum install php54w.x86_64 php54w-cli.x86_64 php54w-common.x86_64 php54w-gd.x86_64 php54w-ldap.x86_64 php54w-mbstring.x86_64 php54w-mcrypt.x86_64 php54w-mysql.x86_64 php54w-pdo.x86_64
• Current PHP version check
• # php -v 
• PHP 5.4.17 (cli) (built: Jul 23 2013 00:02:04) 
• Copyright (c) 1997-2013 The PHP Group 
• Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies

5- Finally
