Hello,
I write plugins for MyBB and I sometimes browse MyBB code. I am always surprised, because MyBB almost always uses PHP functions to typing variables.
Why do not you use cast?
Code is very similar:

$foo = intval($bar);

vs

$foo = (int) $bar;

But cast is 5-6 times faster than using functions, because it's a PHP construction.

Comparsion examples:

I know, it isn't big difference in one case, but MyBB uses inly intval in 1200+ places in the code.
MyBB is big script, so any small changes, can improve overall performance.
