I've been working with PHP for two years now (not by choice) but I still sometimes forget the weird behaviours these not-arrays cause. Recently I was pushing/popping entries in a queue and it fucked the indexing. I had programmed it like I would any other sane language and it wasn't until I was stepping through the bug I realised I had forgotten about this.

I hate PHP for so many more reasons. It baffles me why anyone would think it was a good idea to design it this way. Thankfully my current job involves actively burning it down and preparing for its replacement.
