Result: DiscardedThe test labeled "with key" was the faster by 0.0287 seconds, (3.631% faster)
The with key test took 0.7625 seconds.
The without key test took 0.7913 seconds.
Each test case ran 20 random code order iterations consisting of 149,930 loops for a total of 2,998,600 runs.
- Line execution difference (0.000010) milliseconds.
- Avg difference (1.436) milliseconds per 149,930 loops.
- Total difference 28.73 milliseconds for 2,998,600 loops
The iteration variablity for Code 1 was (11.2305) milliseconds and Code 2 was (11.7503) 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);
