Result: Discarded

The test labeled "===" was the faster by 0.0884 seconds, (7.193% faster)

=== 100%
strcmp() 92.807%

The === test took 1.1409 seconds.
The strcmp() test took 1.2294 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 269,124 loops for a total of 5,382,480 runs.

  • Line execution difference (0.000016) milliseconds.
  • Avg difference (4.421) milliseconds per 269,124 loops.
  • Total difference 88.43 milliseconds for 5,382,480 loops

The iteration variablity for Code 1 was (3.8990) milliseconds and Code 2 was (4.4460) 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;
