I’ve created a repo containing the new PHP 5.2.5 rpms and other extensions.

My yum repo currently only supports i386 architectures and centos / el4.

To upgrade to php 5.2.5 please run:

wget http://www.smudge-it.co.uk/pub/yum/RPM-GPG-KEY-smudge
rpm –import RPM-GPG-KEY-smudge

Add my repository by creating the file
vi /etc/yum.repos.d/smudge.repo

[smudgeit]
name=Smudge IT RPMS for Centos 4 – $basearch
baseurl=http://www.smudge-it.co.uk/pub/yum/centos/4/$basearch/
enabled=1
gpgcheck=1

Then run yum update php.

I have the following files in my repo:

pcre-6.6-1.1.i386.rpm php-gd-5.2.5-1.i386.rpm php-pdo-5.2.5-1.i386.rpm

You can install other extensions such as:

yum install php-eaccelerator
yum install php-suhosin

Edit /etc/php.d/suhosin.ini to->

extension=suhosin.so
suhosin.session.encrypt = Off

Now you have a more secure php installation.
