Result: Discarded

The test labeled "foreach" was the faster by 0.0143 seconds, (1.951% faster)

foreach 100%
for 98.049%

The foreach test took 0.7206 seconds.
The for test took 0.7349 seconds.


Each test case ran 20 random code order iterations consisting of 200,277 loops for a total of 4,005,540 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.717) milliseconds per 200,277 loops.
  • Total difference 14.34 milliseconds for 4,005,540 loops

The iteration variablity for Code 1 was (1.6027) milliseconds and Code 2 was (1.4512) 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;
