Historical ResultsBased on (2) saved test runs, The test labeled "rand()" was (on average) the faster by 0.0152 seconds, (1.365% faster)
The rand() test took 1.0961 seconds.
The array_rand() test took 1.1112 seconds.
Each test case ran 20 random code order iterations consisting of 288,474 loops for a total of 5,769,480 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 288,474 loops.
- Total difference 15.16 milliseconds for 5,769,480 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:
$key = rand(0, count($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];
