Result: DiscardedThe test labeled "without key" was the faster by 0.006 seconds, (1.344% faster)
The without key test took 0.4404 seconds.
The with key test took 0.4464 seconds.
Each test case ran 20 random code order iterations consisting of 121,777 loops for a total of 2,435,540 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.300) milliseconds per 121,777 loops.
- Total difference 6.00 milliseconds for 2,435,540 loops
The iteration variablity for Code 1 was (1.4015) milliseconds and Code 2 was (0.2992) 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);
