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 0.0133 seconds, (1.276% faster)

strcmp() 100%
=== 98.724%

The strcmp() test took 1.0312 seconds.
The === test took 1.0446 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 288,169 loops for a total of 5,763,380 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.666) milliseconds per 288,169 loops.
  • Total difference 13.33 milliseconds for 5,763,380 loops

The iteration variablity for Code 1 was (2.5482) milliseconds and Code 2 was (0.8078) 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;
