Result: SavedThe test labeled "rand()" was the faster by 0.0126 seconds, (1.236% faster)
The rand() test took 1.0033 seconds.
The array_rand() test took 1.0159 seconds.
Each test case ran 20 random code order iterations consisting of 287,035 loops for a total of 5,740,700 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.628) milliseconds per 287,035 loops.
- Total difference 12.55 milliseconds for 5,740,700 loops
The iteration variablity for Code 1 was (0.9099) milliseconds and Code 2 was (0.9431) 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];
