Most likely it failed somewhere in the middle of updating php packages. 
  Leaving you with inconsistent mix of old and new versions of PHP 
packages.  What you might do is to update php by hand, and then finish 
the update process using yum.

First get list of currently installed PHP packages:

   rpm -qa | grep php

Then download them manually from any CentOS mirror (or simply use the 
ones from installation media, they'd get updated when you run yum 
anyhow).  If the php package itself is missing, add it (might be it was 
corrupted or something when update process broke).  You'll probably need 
to force things a bit:

    rpm -Uhv --force --nodeps --oldpackage list-of-rpm-files

Replace "list-of-rpm-files" with filenames of RPM packages you are about 
to reinstall.  The "oldpackage" option is needed if you choose to 
"update" with packages from installation CD-ROM (since those might be 
the older version then some of allready installed packages).

When done, simply re-run "yum update" to finish.
