Variable scope is mediocre at best. For instances:

$array = array(1, 2, 3, 4, 5);

for ($i = 0; $i < 5; $i++)
{
	$num = $array[$i];
	echo $num;
	for ($i = 0; $i < 5; $i++)
	{
		echo $num * $i;
	}
}

The inner loop $i doesn't mask the outer loop $i.
Thus, the whole things gets screwed up.

? This example works perfectly fine. What's your problem here? What do 
you mean with "mask the outer loop"? Of course if you modify $i INSIDE 
the loop the outer one is affected.
