Performance comparison of PHP code alternatives.

Test: === vs. strcmp (fail)

No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "strcmp()" was the faster by 0.0635 seconds, (5.245% faster)

strcmp() 100%
=== 94.755%

The strcmp() test took 1.1472 seconds.
The === test took 1.2107 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 234,482 loops for a total of 4,689,640 runs.

  • Line execution difference (0.000014) milliseconds.
  • Avg difference (3.175) milliseconds per 234,482 loops.
  • Total difference 63.50 milliseconds for 4,689,640 loops

The iteration variablity for Code 1 was (11.0608) milliseconds and Code 2 was (7.4591) 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;
