Result: DiscardedThe test labeled "array_rand()" was the faster by 0.006 seconds, (1.189% faster)
The array_rand() test took 0.497 seconds.
The rand() test took 0.503 seconds.
Each test case ran 20 random code order iterations consisting of 130,227 loops for a total of 2,604,540 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.299) milliseconds per 130,227 loops.
- Total difference 5.98 milliseconds for 2,604,540 loops
The iteration variablity for Code 1 was (3.2104) milliseconds and Code 2 was (2.4668) 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];
