I've noticed someone using the PHP operator === which I can't make sense out of. I've tried it with a function, and it corresponds in crazy ways.

What is the definition of this operator? I can't even find it in the declaration of PHP operators.

$a === $b     (Identical)

TRUE if $a is equal to $b, and they are of the same type. (introduced in PHP 4)
