Result: DiscardedThe test labeled "rand()" was the faster by 0.0515 seconds, (4.567% faster)
The rand() test took 1.0754 seconds.
The array_rand() test took 1.1269 seconds.
Each test case ran 20 random code order iterations consisting of 294,906 loops for a total of 5,898,120 runs.
- Line execution difference (0.000009) milliseconds.
- Avg difference (2.573) milliseconds per 294,906 loops.
- Total difference 51.46 milliseconds for 5,898,120 loops
The iteration variablity for Code 1 was (2.7275) milliseconds and Code 2 was (6.0725) 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];
