How to downgrade PHP to 5.2 on Ubuntu?

Here is a quick script to do this task:

Courtsey of Stijn Beauprez from here:

#! /bin/sh
php_packages=`dpkg -l | grep php | awk ‘{print $2}’`

sudo apt-get remove $php_packages

sed s/lucid/karmic/g /etc/apt/sources.list | sudo tee /etc/apt/sources.list.d/karmic.list

sudo mkdir -p /etc/apt/preferences.d/

for package in $php_packages;
do echo “Package: $package
Pin: release a=karmic
Pin-Priority: 991
” | sudo tee -a /etc/apt/preferences.d/php

sudo apt-get update

sudo apt-get install $php_packages

To undo the script and upgrade to php 5.3 you will need to delete the file (sudo rm /etc/apt/preferences.d/php), run sudo apt-get update, and then sudo apt-get dist-upgrade which will get the latest packages for your distribution, including the PHP packages. (Ben Holt)
