Historical Results

Based on (1) saved test runs, The test labeled "strcmp()" was (on average) the faster by 0.0232 seconds, (3.057% faster)

strcmp() 100%
=== 96.943%

The strcmp() test took 0.7348 seconds.
The === test took 0.758 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 149,303 loops for a total of 2,986,060 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (0.000) milliseconds per 149,303 loops.
  • Total difference 23.17 milliseconds for 2,986,060 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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;
