Result: DiscardedThe test labeled "with key" was the faster by 0.0218 seconds, (2.097% faster)
The with key test took 1.0173 seconds.
The without key test took 1.0391 seconds.
Each test case ran 20 random code order iterations consisting of 284,504 loops for a total of 5,690,080 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (1.090) milliseconds per 284,504 loops.
- Total difference 21.79 milliseconds for 5,690,080 loops
The iteration variablity for Code 1 was (2.2059) milliseconds and Code 2 was (2.6351) 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);
