Result: DiscardedThe test labeled "while (next)" was the faster by 0.0282 seconds, (4.837% faster)
The while (next) test took 0.5553 seconds.
The foreach test took 0.5835 seconds.
Each test case ran 20 random code order iterations consisting of 133,046 loops for a total of 2,660,920 runs.
- Line execution difference (0.000011) milliseconds.
- Avg difference (1.411) milliseconds per 133,046 loops.
- Total difference 28.22 milliseconds for 2,660,920 loops
The iteration variablity for Code 1 was (5.3525) milliseconds and Code 2 was (3.0890) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "foreach", was:
foreach ($GLOBALS['dummy'] as $v) $v + 1;
The second test, "while (next)", was:
reset($GLOBALS['dummy']); while (($v = next($GLOBALS['dummy'])) !== false) $v + 1;
