Downgrading PHP from 5.3 version to 5.2.x on Ubuntu

Question

I'm looking some some way to downgrade php from 5.3 version to 5.2.x on Ubuntu 9.10

Answer 1

Since 5.2.10 is the version that's normally installed under Karmic, so you should just have to remove your version of 5.3 and possibly undo any changes to /etc/apt/sources.list that you made in order to get it installed.

Answer 2

Remove the php-installation, e.g. with aptitude.

Get the sources of the required php version, compile and install it.
