Historical ResultsBased on (4) saved test runs, The test labeled "rand()" was (on average) the faster by 0.0068 seconds, (1.096% faster)
The rand() test took 0.6173 seconds.
The array_rand() test took 0.6241 seconds.
Each test case ran 20 random code order iterations consisting of 171,701 loops for a total of 3,434,015 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 171,701 loops.
- Total difference 6.84 milliseconds for 3,434,015 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];
