Historical Results

Based on (10) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0214 seconds, (2.298% faster)

foreach 100%

for 97.702%

The foreach test took 0.9105 seconds.
The for test took 0.9319 seconds.

Nitty-Gritty

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.

Code

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;
