Result: DiscardedThe test labeled "rand()" was the faster by 0.0605 seconds, (6.759% faster)
The rand() test took 0.8353 seconds.
The array_rand() test took 0.8959 seconds.
Each test case ran 20 random code order iterations consisting of 200,253 loops for a total of 4,005,060 runs.
- Line execution difference (0.000015) milliseconds.
- Avg difference (3.027) milliseconds per 200,253 loops.
- Total difference 60.55 milliseconds for 4,005,060 loops
The iteration variablity for Code 1 was (2.9869) milliseconds and Code 2 was (7.4913) 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];
