[ciapug] PHP 5.2.x : __toString stuff

[David Champion]

The server is owned by another company, I'm doing the work as a 
contractor. They had updated the PHP version a while back without 
telling me, this is the only place in the system (that I've found) where 
this issue cropped up.

We've updated the Dev server to 5.2.6, and will be updating the Live 
server to that version as well.

The "distro" in this case is Windows Server 2003. (Not by my choice).
