Result: DiscardedThe test labeled "rand()" was the faster by 0.0222 seconds, (3.635% faster)
The rand() test took 0.5879 seconds.
The array_rand() test took 0.6101 seconds.
Each test case ran 20 random code order iterations consisting of 137,024 loops for a total of 2,740,480 runs.
- Line execution difference (0.000008) milliseconds.
- Avg difference (1.109) milliseconds per 137,024 loops.
- Total difference 22.18 milliseconds for 2,740,480 loops
The iteration variablity for Code 1 was (5.8143) milliseconds and Code 2 was (4.4321) 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];
