Historical Results

Based on (2) saved test runs, The test labeled "date()" was (on average) the faster by 0.0121 seconds, (1.208% faster)

date() 100%
strftime() 98.792%

The date() test took 0.9868 seconds.
The strftime() test took 0.9989 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 274,258 loops for a total of 5,485,160 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 274,258 loops.
  • Total difference 12.06 milliseconds for 5,485,160 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, "date()", was:

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = date('Y-m-d \\a\\t H:i:s', $GLOBALS['t']);

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

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = strftime('%Y-%m-%d at %H:%M:%S', $GLOBALS['t']);
