Result: DiscardedThe test labeled "rand()" was the faster by 0.0272 seconds, (3.527% faster)
The rand() test took 0.7443 seconds.
The array_rand() test took 0.7715 seconds.
Each test case ran 20 random code order iterations consisting of 188,212 loops for a total of 3,764,240 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (1.361) milliseconds per 188,212 loops.
- Total difference 27.21 milliseconds for 3,764,240 loops
The iteration variablity for Code 1 was (1.2602) milliseconds and Code 2 was (1.7778) 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];
