I just spent a good few minutes looking for a bug which was, really (as they usually are) really obvious.
This is the first time I’ve written any PHP in a good few weeks, and since then I’d been using C loads of even JavaScript a little.
Well, variables in PHP look $likeThis, while more likeThis in C or JavaScript.
The dollar sign is the clear difference, but (it seems) it’s easy to forget. Hopefully writing this post will help me to remember!
