Result: DiscardedThe test labeled "array_rand()" was the faster by 0.0036 seconds, (0.331% faster)
The array_rand() test took 1.083 seconds.
The rand() test took 1.0866 seconds.
Each test case ran 20 random code order iterations consisting of 282,730 loops for a total of 5,654,600 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.180) milliseconds per 282,730 loops.
- Total difference 3.59 milliseconds for 5,654,600 loops
The iteration variablity for Code 1 was (2.7627) milliseconds and Code 2 was (2.2343) 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];
