Result: Discarded

The test labeled "strcmp()" was the faster by 0.058 seconds, (5.021% faster)

strcmp() 100%
=== 94.979%

The strcmp() test took 1.0973 seconds.
The === test took 1.1553 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 205,376 loops for a total of 4,107,520 runs.

  • Line execution difference (0.000014) milliseconds.
  • Avg difference (2.901) milliseconds per 205,376 loops.
  • Total difference 58.01 milliseconds for 4,107,520 loops

The iteration variablity for Code 1 was (10.7299) milliseconds and Code 2 was (10.3302) 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;
