Result: Discarded

The test labeled "===" was the faster by 0.0121 seconds, (2.340% faster)

=== 100%
== 97.66%

The === test took 0.5038 seconds.
The == test took 0.5159 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 125,409 loops for a total of 2,508,180 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.603) milliseconds per 125,409 loops.
  • Total difference 12.07 milliseconds for 2,508,180 loops

The iteration variablity for Code 1 was (1.5845) milliseconds and Code 2 was (0.5104) 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'] = $GLOBALS['dummy1'] === $GLOBALS['dummy2'];
