Result: Discarded

The test labeled "===" was the faster by 0.0445 seconds, (8.505% faster)

=== 100%
strcmp() 91.495%

The === test took 0.4793 seconds.
The strcmp() test took 0.5238 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 121,415 loops for a total of 2,428,300 runs.

  • Line execution difference (0.000018) milliseconds.
  • Avg difference (2.227) milliseconds per 121,415 loops.
  • Total difference 44.55 milliseconds for 2,428,300 loops

The iteration variablity for Code 1 was (2.5842) milliseconds and Code 2 was (4.3186) 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, "strcmp()", was:

for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy3'] = strcmp($GLOBALS['dummy1'], $GLOBALS['dummy2']) == 0;
