Historical ResultsBased on (4) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0116 seconds, (1.223% faster)
The foreach test took 0.9362 seconds.
The while (next) test took 0.9478 seconds.
Each test case ran 20 random code order iterations consisting of 223,453 loops for a total of 4,469,055 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 223,453 loops.
- Total difference 11.59 milliseconds for 4,469,055 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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;
