how to upgrade PHP 5.1 To 5.2 centos

This guide describes how to upgrade the standard PHP 5.1.x packages in CentOS 5.x 32-bit to the current development versions 5.2.x. These instructions were created using CentOS 5.3 32-bit and with the following PHP packages installed:

# rpm -qa |grep php

 php-5.1.6-15.el5.i386
 php-pdo-5.1.6-15.el5.i386
 php-bcmath-5.1.6-15.el5.i386
 php-ldap-5.1.6-15.el5.i386
 php-devel-5.1.6-15.el5.i386
 php-gd-5.1.6-15.el5.i386
 php-xml-5.1.6-15.el5.i386
 php-mbstring-5.1.6-15.el5.i386
 php-mysql-5.1.6-15.el5.i386
 php-dba-5.1.6-15.el5.i386
