just need php5.2

[motokochan]

You can use PHP 5.2 if you want, but you'll need to find a repository with it or compile it yourself.

I know the REMI archives have PHP 5.2, but you'll have to download all the components manually plus it's an older 5.2 version with security bugs.

RPMForge follows EL5, so they only have extra modules for the base 5.1.6.
