Result: Discarded
The test labeled "rand()" was the faster by 0.0606 seconds, (5.610% faster)
The rand() test took 1.0189 seconds.
The mt_rand() test took 1.0795 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 251,457 loops for a total of 5,029,140 runs.
- Line execution difference (0.000012) milliseconds.
- Avg difference (3.028) milliseconds per 251,457 loops.
- Total difference 60.56 milliseconds for 5,029,140 loops
The iteration variablity for Code 1 was (4.6553) milliseconds and Code 2 was (8.9480) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "rand()", was:
$GLOBALS['dummy'] = rand(0, 1000);
The second test, "mt_rand()", was:
$GLOBALS['dummy'] = mt_rand(0, 1000);
