Historical ResultsBased on (2) saved test runs, The test labeled "rand()" was (on average) the faster by 0.0194 seconds, (2.809% faster)
The rand() test took 0.6721 seconds.
The array_rand() test took 0.6915 seconds.
Each test case ran 20 random code order iterations consisting of 182,184 loops for a total of 3,643,670 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.000) milliseconds per 182,184 loops.
- Total difference 19.42 milliseconds for 3,643,670 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:
$keys = array_keys($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];
