Result: DiscardedThe test labeled "rand()" was the faster by 0.0106 seconds, (1.489% faster)
The rand() test took 0.7042 seconds.
The array_rand() test took 0.7148 seconds.
Each test case ran 20 random code order iterations consisting of 146,500 loops for a total of 2,930,000 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.532) milliseconds per 146,500 loops.
- Total difference 10.64 milliseconds for 2,930,000 loops
The iteration variablity for Code 1 was (2.1213) milliseconds and Code 2 was (2.9809) 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];
