if(0 == '%') echo "WTF, Php, why can't you compare things sanely?"

Question

I just reduced a crazy bug to what's in the title of this question. I'm sure there's a Perfectly Reasonable Explanation for why Php thinks that 0 == '%' (or any other special character, I think). I thought it would be good to get that explanation on StackOverflow!

Answer 1

It will do the same to any string, converting a non-number string to integer always gives 0.
