Question

I remember that there were function that have such functionality. Unfortunately, I don’t remember the name of it. Basically, it did something like…

$values = foo(array('x', 'y', 'z'), $_POST);

If there are such keys in the array, it does return new array (named $values) with only those keys… taken from $_POST. If one or more keys aren’t in $_POST, it simply returns false.

Anyone remember something like that or I was just dreaming? Thanks in advice!
