The test labeled "===" was the faster by 0.0178 seconds, (1.704% faster)

=== 100%
strcmp() 98.296%

The === test took 1.0293 seconds.
The strcmp() test took 1.0472 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 271,783 loops for a total of 5,435,660 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.892) milliseconds per 271,783 loops.
  • Total difference 17.85 milliseconds for 5,435,660 loops

The iteration variablity for Code 1 was (2.5037) milliseconds and Code 2 was (2.3639) 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;
