Result: DiscardedThe test labeled "rand()" was the faster by 0.0025 seconds, (0.229% faster)
The rand() test took 1.0981 seconds.
The array_rand() test took 1.1006 seconds.
Each test case ran 20 random code order iterations consisting of 296,731 loops for a total of 5,934,620 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.126) milliseconds per 296,731 loops.
- Total difference 2.52 milliseconds for 5,934,620 loops
The iteration variablity for Code 1 was (4.1819) milliseconds and Code 2 was (3.7200) 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];
