Result: SavedThe test labeled "without key" was the faster by 0.0027 seconds, (0.417% faster)
The without key test took 0.6442 seconds.
The with key test took 0.6469 seconds.
Each test case ran 20 random code order iterations consisting of 142,542 loops for a total of 2,850,840 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.135) milliseconds per 142,542 loops.
- Total difference 2.70 milliseconds for 2,850,840 loops
The iteration variablity for Code 1 was (6.9819) milliseconds and Code 2 was (6.9612) 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);
