Result: DiscardedThe test labeled "while (next)" was the faster by 0.0233 seconds, (2.076% faster)
The while (next) test took 1.1013 seconds.
The foreach test took 1.1247 seconds.
Each test case ran 20 random code order iterations consisting of 276,031 loops for a total of 5,520,620 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (1.167) milliseconds per 276,031 loops.
- Total difference 23.34 milliseconds for 5,520,620 loops
The iteration variablity for Code 1 was (4.8669) milliseconds and Code 2 was (4.1469) 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;
