Result: DiscardedThe test labeled "rand()" was the faster by 0.039 seconds, (2.498% faster)
The rand() test took 1.5213 seconds.
The array_rand() test took 1.5603 seconds.
Each test case ran 20 random code order iterations consisting of 128,570 loops for a total of 2,571,400 runs.
- Line execution difference (0.000015) milliseconds.
- Avg difference (1.949) milliseconds per 128,570 loops.
- Total difference 38.98 milliseconds for 2,571,400 loops
The iteration variablity for Code 1 was (39.2805) milliseconds and Code 2 was (39.8372) 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];
