== 100%

=== 99.235%

The == test took 1.155 seconds.
The === test took 1.1639 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 283,064 loops for a total of 5,661,280 runs.

Line execution difference (0.000002) milliseconds.
Avg difference (0.445) milliseconds per 283,064 loops.
Total difference 8.90 milliseconds for 5,661,280 loops

The iteration variablity for Code 1 was (7.7902) milliseconds and Code 2 was (6.3610) 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'];
