Schlossnagle (in "Advanced PHP Programming") advises:

$i = 0; while ($i < $j)
	{
	........
	++$i;
	}

rather than:

$i = 0; while ($i < $j)
	{
	.......
	$i++;
	}

as the former apparently uses less memory references.  However I find it very hard to
believe that the difference would ever show up in the real world.
