Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 282,968 loops for a total of 5,659,360 runs.

Line execution difference (0.000005) milliseconds.
Avg difference (1.334) milliseconds per 282,968 loops.
Total difference 26.69 milliseconds for 5,659,360 loops

The iteration variablity for Code 1 was (1.4347) milliseconds and Code 2 was (1.5375) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "==", was:

for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy3'] = $GLOBALS['dummy1'] == $GLOBALS['dummy2'];

The second test, "===", was:

for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy3'] = (int) $GLOBALS['dummy1'] === (int) $GLOBALS['dummy2'];
