View test history (26) Run this test again Return to test menu

Result: Discarded

The test labeled "strtotime('now')" was the faster by 0.014 seconds, (1.458% faster)

strtotime('now') 100%
time() 98.542%

The strtotime('now') test took 0.9483 seconds.
The time() test took 0.9624 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 263,917 loops for a total of 5,278,340 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.702) milliseconds per 263,917 loops.
  • Total difference 14.03 milliseconds for 5,278,340 loops

The iteration variablity for Code 1 was (3.6504) milliseconds and Code 2 was (1.9459) 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');
