Result: DiscardedThe test labeled "rand()" was the faster by 0.002 seconds, (0.172% faster)
The rand() test took 1.1775 seconds.
The array_rand() test took 1.1796 seconds.
Each test case ran 20 random code order iterations consisting of 286,056 loops for a total of 5,721,120 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.102) milliseconds per 286,056 loops.
- Total difference 2.03 milliseconds for 5,721,120 loops
The iteration variablity for Code 1 was (7.7819) milliseconds and Code 2 was (7.2406) 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];
