I tried updating php through the Mandrake Control Center and all I got was a couple updates for php 4.3.8. I know that the php website says you should upgrade to 4.3.11 as soon as possible because aparantly that version fixed some bugs but I can't seem to find any instructions.
I just found this neat document http://speculation.org/garrick/urpmifaq.txt
which more or less explains the ins and outs of urpmi and according to that document and easyurpmi I seem to have the proper media and directories configured so when I run urpmi apache2-mod_php, it should return any updates if they are available. Since this returns nothing it should be safe to say that there are no updates at this time.
I think I may have answered my own question but if there is anything else I should know please feel free to tell me
