[root@www4 ~]# rpm -qa | grep php

Thank you for the link. I looked at that article, but noticed I was not getting those same errors. I was getting a no packages marked for update error.

Linux 2.6.18-194.26.1.el5
GenuineIntel, Intel(R) Pentium(R) 4 CPU 2.80GHz

I really need to upgrade php to 5.3, yet am not having any luck on any front. Tried updating through yum, but says no upgrades available, yet see the list...
