Historical Results

Based on (11) saved test runs, The test labeled "time()" was (on average) the faster by 0.0094 seconds, (1.182% faster)

time() 100%
strtotime('now') 98.818%

The time() test took 0.7864 seconds.
The strtotime('now') test took 0.7958 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 204,003 loops for a total of 4,080,055 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 204,003 loops.
  • Total difference 9.41 milliseconds for 4,080,055 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, "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');
