No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "time()" was the faster by 0.046 seconds, (6.286% faster)

time() 100%

microtime(true) 93.714%

The time() test took 0.6858 seconds.
The microtime(true) test took 0.7319 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 180,361 loops for a total of 3,607,220 runs.

Line execution difference (0.000013) milliseconds.
Avg difference (2.300) milliseconds per 180,361 loops.
Total difference 46.01 milliseconds for 3,607,220 loops

The iteration variablity for Code 1 was (3.1858) milliseconds and Code 2 was (5.2877) 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, "microtime(true)", was:

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