The test labeled "time()" was the faster by 0.0157 seconds, (3.331% faster)

time() 100%

microtime(true) 96.669%

The time() test took 0.4557 seconds.
The microtime(true) test took 0.4714 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 132,239 loops for a total of 2,644,780 runs.

Line execution difference (0.000006) milliseconds.
Avg difference (0.785) milliseconds per 132,239 loops.
Total difference 15.70 milliseconds for 2,644,780 loops

The iteration variablity for Code 1 was (0.1272) milliseconds and Code 2 was (0.2383) 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);
