Upgrading to PHP 5.2.5 on RHEL and CentOS

After a little more than 2 months of waiting since the last release, PHP has been updated once again, this time to 5.2.5. The 5.2.5 release brings several security enhancements, more than 60 bug fixes, and improved performance for those of you that like arrays (and really, who doesn't?).

It doesn't go in your 'wp-content/plugins' folder (that was the first mistake I made, I never read the directions), it doesn't show up in your plugins list (making you check manually for updates, even under WordPress 2.3), and it doesn't have a pretty GUI in 'wp-admin'.

What it does do is eliminate a number of common queries that get run over and over for every single page view. On this site it eliminated a total of 8 queries per page load. While that only dropped the page generation time by about 0.1 seconds, every little bit counts.
