Result: DiscardedThe test labeled "rand()" was the faster by 0.0128 seconds, (1.197% faster)
The rand() test took 1.0539 seconds.
The array_rand() test took 1.0666 seconds.
Each test case ran 20 random code order iterations consisting of 280,367 loops for a total of 5,607,340 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.638) milliseconds per 280,367 loops.
- Total difference 12.77 milliseconds for 5,607,340 loops
The iteration variablity for Code 1 was (4.1507) milliseconds and Code 2 was (3.9310) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "rand()", was:
$keys = array_keys($GLOBALS['array']); $key = rand(0, count($keys) - 1); $GLOBALS['dummy'] = $GLOBALS['array'][$keys[$key]];
The second test, "array_rand()", was:
$key = array_rand($GLOBALS['array'], 1); $GLOBALS['dummy'] = $GLOBALS['array'][$key];
