Result: Discarded

The test labeled "strtotime('now')" was the faster by 0.0347 seconds, (2.995% faster)

strtotime('now') 100%
time() 97.005%

The strtotime('now') test took 1.1234 seconds.
The time() test took 1.1581 seconds.


Each test case ran 20 random code order iterations consisting of 287,281 loops for a total of 5,745,620 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (1.734) milliseconds per 287,281 loops.
  • Total difference 34.69 milliseconds for 5,745,620 loops

The iteration variablity for Code 1 was (7.4186) milliseconds and Code 2 was (5.6694) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "time()", was:

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = time();

The second test, "strtotime('now')", was:

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = strtotime('now');
