The test labeled "==" was the faster by 0.1121 seconds, (11.839% faster)

== 100%
=== 88.161%

The == test took 0.8347 seconds.
The === test took 0.9467 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 135,398 loops for a total of 2,707,960 runs.

  • Line execution difference (0.000041) milliseconds.
  • Avg difference (5.604) milliseconds per 135,398 loops.
  • Total difference 112.08 milliseconds for 2,707,960 loops

The iteration variablity for Code 1 was (6.0575) milliseconds and Code 2 was (6.0187) 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'];
