Result: DiscardedThe test labeled "array_rand()" was the faster by 0.0015 seconds, (0.137% faster)
The array_rand() test took 1.094 seconds.
The rand() test took 1.0955 seconds.
Each test case ran 20 random code order iterations consisting of 290,012 loops for a total of 5,800,240 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.075) milliseconds per 290,012 loops.
- Total difference 1.50 milliseconds for 5,800,240 loops
The iteration variablity for Code 1 was (4.3095) milliseconds and Code 2 was (3.8294) 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];
