The next version of PHP, which I am running here now, makes PHP a stricter language. That's good, but when you've been writing code for a long time sometimes you do not realize you are doing something wrong if it works. That has been the case here. I noticed some PHP warnings showing up a few weeks ago here. They had upgraded PHP to the latest RC, which I unfortunately run PHP 5.3 on my developer machine (not for long). The code on this site was almost a year old and I checked the code I would be uploading to check for any coding errors. It looked correct in my dev code. Unfortunately I had a class method returning a string, but some code that was using was older and expected an array. This was cauing warnings to show up, as it was being treated as an array, which is wrong.
