Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 266,051 loops for a total of 5,321,020 runs.

Line execution difference (0.000009) milliseconds.
Avg difference (2.453) milliseconds per 266,051 loops.
Total difference 49.07 milliseconds for 5,321,020 loops

The iteration variablity for Code 1 was (11.6201) milliseconds and Code 2 was (9.3965) 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);
