Historical ResultsBased on (6) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0463 seconds, (4.233% faster)
The foreach test took 1.0474 seconds.
The while (next) test took 1.0937 seconds.
Each test case ran 20 random code order iterations consisting of 191,417 loops for a total of 3,828,343 runs.
- Line execution difference (0.000012) milliseconds.
- Avg difference (0.000) milliseconds per 191,417 loops.
- Total difference 46.30 milliseconds for 3,828,343 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;
