Result: DiscardedThe test labeled "without key" was the faster by 0.0104 seconds, (1.844% faster)
The without key test took 0.5551 seconds.
The with key test took 0.5655 seconds.
Each test case ran 20 random code order iterations consisting of 134,843 loops for a total of 2,696,860 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.521) milliseconds per 134,843 loops.
- Total difference 10.43 milliseconds for 2,696,860 loops
The iteration variablity for Code 1 was (4.1421) milliseconds and Code 2 was (3.2553) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "with key", was:
foreach ($GLOBALS['dummy'] as $k => $v) $v + array(1);
The second test, "without key", was:
foreach ($GLOBALS['dummy'] as $v) $v + array(1);
