Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 194,554 loops for a total of 3,891,073 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.000) milliseconds per 194,554 loops.
  • Total difference 13.71 milliseconds for 3,891,073 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, "strtotime('today')", was:

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = strtotime('today', $GLOBALS['t']);

The second test, "mktime()", was:

for ($i = 0; $i < 100; $i++)
{
	$temp = localtime($GLOBALS['t'], true);
	$GLOBALS['dummy'] = mktime($temp['tm_hour'], $temp['tm_min'], $temp['tm_sec'], $temp['tm_mon'] + 1, $temp['tm_mday'] + 1, 1900 + $temp['tm_year']);
}
