Result: DiscardedThe test labeled "rand()" was the faster by 0.0049 seconds, (0.689% faster)
The rand() test took 0.7083 seconds.
The array_rand() test took 0.7132 seconds.
Each test case ran 20 random code order iterations consisting of 147,052 loops for a total of 2,941,040 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.246) milliseconds per 147,052 loops.
- Total difference 4.91 milliseconds for 2,941,040 loops
The iteration variablity for Code 1 was (4.7845) milliseconds and Code 2 was (4.3581) 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];
