The test labeled "for" was the faster by 0.0036 seconds, (0.306% faster)

for 100%

foreach 99.694%

The for test took 1.1826 seconds.
The foreach test took 1.1863 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 286,056 loops for a total of 5,721,120 runs.

Line execution difference (0.000001) milliseconds.
Avg difference (0.181) milliseconds per 286,056 loops.
Total difference 3.62 milliseconds for 5,721,120 loops

The iteration variablity for Code 1 was (6.9600) milliseconds and Code 2 was (6.6369) 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;
