Result: DiscardedThe test labeled "rand()" was the faster by 0.0143 seconds, (1.212% faster)
The rand() test took 1.1674 seconds.
The array_rand() test took 1.1817 seconds.
Each test case ran 20 random code order iterations consisting of 277,034 loops for a total of 5,540,680 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.716) milliseconds per 277,034 loops.
- Total difference 14.32 milliseconds for 5,540,680 loops
The iteration variablity for Code 1 was (6.5464) milliseconds and Code 2 was (4.5390) 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];
