Result: DiscardedThe test labeled "rand()" was the faster by 0.0758 seconds, (11.999% faster)
The rand() test took 0.5561 seconds.
The array_rand() test took 0.6319 seconds.
Each test case ran 20 random code order iterations consisting of 138,999 loops for a total of 2,779,980 runs.
- Line execution difference (0.000027) milliseconds.
- Avg difference (3.791) milliseconds per 138,999 loops.
- Total difference 75.82 milliseconds for 2,779,980 loops
The iteration variablity for Code 1 was (2.4741) milliseconds and Code 2 was (4.9569) 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];
