Historical ResultsBased on (2) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0113 seconds, (1.082% faster)
The foreach test took 1.0367 seconds.
The for test took 1.048 seconds.
Each test case ran 20 random code order iterations consisting of 264,669 loops for a total of 5,293,380 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 264,669 loops.
- Total difference 11.34 milliseconds for 5,293,380 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) $v + 1;
The second test, "for", was:
for ($k = 0, $n = count($GLOBALS['dummy']); $k < $n; $k++) $GLOBALS['dummy'][$k] + 1;
