cafespainWell, I've just spent almost an entire day building and rebuilding PHP for Litespeed and then wondering why none of the changes I made had an effect on the installation.
Finally I built a little plugin that added a PHP Info page to the site admin menu to see just exactly what was being loaded. It turned out the symbolic link to the php binary wasn't being updated properly and it was still running an earlier version.
So here it is, I hope it helps some of you retain your hair-line.

Click the Get code link and paste into a text file. It'll work as a standard plugin or in mu-plugins.
