Result: DiscardedThe test labeled "with key" was the faster by 0.0097 seconds, (1.255% faster)
The with key test took 0.7612 seconds.
The without key test took 0.7709 seconds.
Each test case ran 20 random code order iterations consisting of 174,001 loops for a total of 3,480,020 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.484) milliseconds per 174,001 loops.
- Total difference 9.68 milliseconds for 3,480,020 loops
The iteration variablity for Code 1 was (1.8787) milliseconds and Code 2 was (2.3498) 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);
