Is it possible to downgrade PHP from 5.4.17 to 5.3.x

I just accepted a yum update that upgraded PHP to 5.4.17 and it is causing a bunch of problems for me. Is it possible to downgrade back to 5.3.x and if so, how?

PHP 5.3 packages are available from the Nucleus repository: https://www.atomicorp.com/products/nucleus.html

PHP 5.3 src.rpms are available on all the mirrors under the /source/ directory (ex: www.atomicorp.com/channels/source/php/)

Thanks for the info. This may seem like a stupid question but I have always been confused by tangled dependencies and how to get around them. Would it be safe to just simply remove all the packages one by one by forcing and using nodeps then start installing all the new rpms in any order ignoring deps? Or is there a proper way to do this?

sure thats a way to do it. Normally if Im trying to skip a inter-relationship between packages I'll use --nodeps. Like if its a plesk box for example, you'd want to skip that check so it wouldnt remove the psa-* packages. Then you could just re-install with yum like normal

Protip: download the packages via "yumdownloader" beforehand, so you can quickly install with "yum localinstall", by which you minimize the "PHP downtime".

See http://www.atomicorp.com/forum/viewtopic.php?f=2&t=7037 for downgrade instructions.

But I strongly recommend using the Neucleus repo for 5.3 if possible instead of stock Centos. Scott's php is better, and you don't lose mcrypt/eaccelerator etc.
