Result: DiscardedThe test labeled "rand()" was the faster by 0.0631 seconds, (8.236% faster)
The rand() test took 0.7036 seconds.
The array_rand() test took 0.7667 seconds.
Each test case ran 20 random code order iterations consisting of 153,792 loops for a total of 3,075,840 runs.
- Line execution difference (0.000021) milliseconds.
- Avg difference (3.157) milliseconds per 153,792 loops.
- Total difference 63.15 milliseconds for 3,075,840 loops
The iteration variablity for Code 1 was (5.1321) milliseconds and Code 2 was (5.5873) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "rand()", was:
$key = rand(0, count($GLOBALS['array']) - 1); $GLOBALS['dummy'] = $GLOBALS['array'][$key];
The second test, "array_rand()", was:
$key = array_rand($GLOBALS['array'], 1); $GLOBALS['dummy'] = $GLOBALS['array'][$key];
