Historical ResultsBased on (10) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0214 seconds, (2.298% faster)
The foreach test took 0.9105 seconds.
The for test took 0.9319 seconds.
Each test case ran 20 random code order iterations consisting of 201,374 loops for a total of 4,027,484 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.000) milliseconds per 201,374 loops.
- Total difference 21.41 milliseconds for 4,027,484 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:
$range = range(0, 100); foreach ($range as $n) $GLOBALS['dummy'] = $n;
The second test, "for", was:
for ($n = 0; $n <= 100; $n++) $GLOBALS['dummy'] = $n;
