Result: DiscardedThe test labeled "array_rand()" was the faster by 0.0189 seconds, (1.553% faster)
The array_rand() test took 1.1988 seconds.
The rand() test took 1.2177 seconds.
Each test case ran 20 random code order iterations consisting of 291,321 loops for a total of 5,826,420 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.945) milliseconds per 291,321 loops.
- Total difference 18.91 milliseconds for 5,826,420 loops
The iteration variablity for Code 1 was (8.7800) milliseconds and Code 2 was (7.3234) 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];
