Result: Discarded

The test labeled "foreach" was the faster by 0.0032 seconds, (0.568% faster)

foreach 100%
for 99.432%

The foreach test took 0.5613 seconds.
The for test took 0.5645 seconds.


Each test case ran 20 random code order iterations consisting of 126,401 loops for a total of 2,528,020 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.160) milliseconds per 126,401 loops.
  • Total difference 3.21 milliseconds for 2,528,020 loops

The iteration variablity for Code 1 was (2.1740) milliseconds and Code 2 was (1.9428) 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;
