Result: DiscardedThe test labeled "while (next)" was the faster by 0.0131 seconds, (1.298% faster)
The while (next) test took 0.9983 seconds.
The foreach test took 1.0114 seconds.
Each test case ran 20 random code order iterations consisting of 233,308 loops for a total of 4,666,160 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.656) milliseconds per 233,308 loops.
- Total difference 13.13 milliseconds for 4,666,160 loops
The iteration variablity for Code 1 was (5.1006) milliseconds and Code 2 was (3.8136) 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;
