Result: DiscardedThe test labeled "rand()" was the faster by 0.1238 seconds, (10.450% faster)
The rand() test took 1.0611 seconds.
The array_rand() test took 1.1849 seconds.
Each test case ran 20 random code order iterations consisting of 276,486 loops for a total of 5,529,720 runs.
- Line execution difference (0.000022) milliseconds.
- Avg difference (6.191) milliseconds per 276,486 loops.
- Total difference 123.82 milliseconds for 5,529,720 loops
The iteration variablity for Code 1 was (3.2243) milliseconds and Code 2 was (9.3046) 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];
