Ubuntu – How to downgrade from PHP 5.3 to PHP 5.2 on Ubuntu Server 10.10

I've had success with these packages :)

Hope it helps!

The excellent Remi has the very latest PHP builds for legacy distros - I upgraded Fedora 6 to PHP 5.3 recently. Once you have installed the key as above, you can install PHP 5.3.1 like so:

yum --enablerepo=remi update php-\*

This will not affect normal upgrade/installation from standard repos, as "remi" is a separate repo and not active except for during this single request.
