View test history (18) Run this test again Return to test menu

Result: Discarded

The test labeled "strtotime('now')" was the faster by 0.0239 seconds, (3.074% faster)

strtotime('now') 100%
time() 96.926%

The strtotime('now') test took 0.7543 seconds.
The time() test took 0.7782 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 162,114 loops for a total of 3,242,280 runs.

  • Line execution difference (0.000007) milliseconds.
  • Avg difference (1.196) milliseconds per 162,114 loops.
  • Total difference 23.93 milliseconds for 3,242,280 loops

The iteration variablity for Code 1 was (4.9777) milliseconds and Code 2 was (5.3043) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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');
