Result: DiscardedThe test labeled "with key" was the faster by 0.0066 seconds, (0.628% faster)
The with key test took 1.0442 seconds.
The without key test took 1.0508 seconds.
Each test case ran 20 random code order iterations consisting of 274,406 loops for a total of 5,488,120 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.330) milliseconds per 274,406 loops.
- Total difference 6.60 milliseconds for 5,488,120 loops
The iteration variablity for Code 1 was (2.0979) milliseconds and Code 2 was (1.6827) 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);
