Historical ResultsBased on (2) saved test runs, The test labeled "rand()" was (on average) the faster by 0.007 seconds, (0.903% faster)
The rand() test took 0.7702 seconds.
The array_rand() test took 0.7773 seconds.
Each test case ran 20 random code order iterations consisting of 213,831 loops for a total of 4,276,620 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 213,831 loops.
- Total difference 7.02 milliseconds for 4,276,620 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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];
