Result: DiscardedThe test labeled "with key" was the faster by 0.0014 seconds, (0.295% faster)
The with key test took 0.4652 seconds.
The without key test took 0.4666 seconds.
Each test case ran 20 random code order iterations consisting of 117,462 loops for a total of 2,349,240 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.069) milliseconds per 117,462 loops.
- Total difference 1.38 milliseconds for 2,349,240 loops
The iteration variablity for Code 1 was (2.0262) milliseconds and Code 2 was (2.6293) 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);
