Historical ResultsBased on (3) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0286 seconds, (2.853% faster)
The foreach test took 0.973 seconds.
The while (next) test took 1.0015 seconds.
Each test case ran 20 random code order iterations consisting of 184,668 loops for a total of 3,693,367 runs.
- Line execution difference (0.000008) milliseconds.
- Avg difference (0.000) milliseconds per 184,668 loops.
- Total difference 28.58 milliseconds for 3,693,367 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;
