Result: DiscardedThe test labeled "without key" was the faster by 0.0252 seconds, (2.115% faster)
The without key test took 1.1641 seconds.
The with key test took 1.1892 seconds.
Each test case ran 20 random code order iterations consisting of 270,949 loops for a total of 5,418,980 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (1.258) milliseconds per 270,949 loops.
- Total difference 25.16 milliseconds for 5,418,980 loops
The iteration variablity for Code 1 was (9.7607) milliseconds and Code 2 was (10.1812) 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);
