Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 279,434 loops for a total of 5,588,680 runs.

Line execution difference (0.000008) milliseconds.
Avg difference (2.131) milliseconds per 279,434 loops.
Total difference 42.61 milliseconds for 5,588,680 loops

The iteration variablity for Code 1 was (5.3021) milliseconds and Code 2 was (1.7627) 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'];
