Historical Results

Based on (6) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0149 seconds, (1.663% faster)

foreach 100%
for 98.337%

The foreach test took 0.8807 seconds.
The for test took 0.8956 seconds.


Each test case ran 20 random code order iterations consisting of 231,654 loops for a total of 4,633,083 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 231,654 loops.
  • Total difference 14.89 milliseconds for 4,633,083 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;
