Yeah, the implicit casting in PHP is bonkers, especially when it comes to comparisons. The comparison table looks like the scribblings of a madman: https://www.php.net/manual/en/types.comparisons.php

(though granted, Javascript acts very similarly.)

I have no hate for PHP, it’s been a tool in my toolbox for over a decade, I think it has a lot of good qualities, and it has made me a lot of money.

That said, after ten years of use, I still see something like:

    function_returning_false_or_int() > -1

And sometimes have the wrong intuition about what it does.

Now, nobody should write that shit in the first place, but turns out it’s equivalent to ‘!== false’.

‘(int)false’ is zero, but ‘false > -1’... is not true.
