The === test took 0.621 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 168,243 loops for a total of 3,364,860 runs.

Line execution difference (0.000001) milliseconds.
Avg difference (0.195) milliseconds per 168,243 loops.
Total difference 3.91 milliseconds for 3,364,860 loops

The iteration variablity for Code 1 was (0.9212) milliseconds and Code 2 was (0.4320) 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'];
