Result: Discarded

The test labeled "mktime()" was the faster by 0.0102 seconds, (1.022% faster)

mktime() 100%
strtotime('today') 98.978%

The mktime() test took 0.989 seconds.
The strtotime('today') test took 0.9992 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 265,084 loops for a total of 5,301,680 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.511) milliseconds per 265,084 loops.
  • Total difference 10.21 milliseconds for 5,301,680 loops

The iteration variablity for Code 1 was (3.5826) milliseconds and Code 2 was (2.8264) 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']);
}
