Please note these are not the official packages, and have been put together by http://rpms.famillecollet.com/ for RHEL5 distributions (thank you!). I have rebuilt these so they install for ClearOS with the addition of two RPM's (libedit and sqlite2).

You can also install many other PHP features through YUM.

yum install php-* 

yum list php-* 

for all the available extensions you can add.

yum --enablerepo=timb upgrade php

yum remove php-*
