Result: DiscardedThe test labeled "array_rand()" was the faster by 0 seconds, (0.001% faster)
The array_rand() test took 0.5421 seconds.
The rand() test took 0.5421 seconds.
Each test case ran 20 random code order iterations consisting of 125,137 loops for a total of 2,502,740 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.000) milliseconds per 125,137 loops.
- Total difference 0.00 milliseconds for 2,502,740 loops
The iteration variablity for Code 1 was (4.9099) milliseconds and Code 2 was (4.0568) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "rand()", was:
$key = rand(0, count($GLOBALS['array']) - 1); $GLOBALS['dummy'] = $GLOBALS['array'][$key];
The second test, "array_rand()", was:
$key = array_rand($GLOBALS['array'], 1); $GLOBALS['dummy'] = $GLOBALS['array'][$key];
