Result: DiscardedThe test labeled "array_rand()" was the faster by 0.049 seconds, (4.204% faster)
The array_rand() test took 1.1167 seconds.
The rand() test took 1.1657 seconds.
Each test case ran 20 random code order iterations consisting of 268,392 loops for a total of 5,367,840 runs.
- Line execution difference (0.000009) milliseconds.
- Avg difference (2.450) milliseconds per 268,392 loops.
- Total difference 49.01 milliseconds for 5,367,840 loops
The iteration variablity for Code 1 was (7.8351) milliseconds and Code 2 was (6.0229) 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];
