Result: DiscardedThe test labeled "without key" was the faster by 0.069 seconds, (6.367% faster)
The without key test took 1.0144 seconds.
The with key test took 1.0834 seconds.
Each test case ran 20 random code order iterations consisting of 207,767 loops for a total of 4,155,340 runs.
- Line execution difference (0.000017) milliseconds.
- Avg difference (3.449) milliseconds per 207,767 loops.
- Total difference 68.99 milliseconds for 4,155,340 loops
The iteration variablity for Code 1 was (10.8387) milliseconds and Code 2 was (8.4457) 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);
