[PHP] Upgrading PHP 4.1.2 to Current

[Davy Campano]

I am pretty new to Linux and I was wondering if someone can point me in the right 
direction on upgrading packages.  Right now, I am looking to upgrade PHP but actually 
I would just like to understand how to do any upgrades.  Do I have to recompile???  If 
so, how do I do this?  Thanks for any help!
