The test labeled "foreach" was the faster by 0.0233 seconds, (1.992% faster)

foreach 100%
for 98.008%

The foreach test took 1.1438 seconds.
The for test took 1.1671 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 271,739 loops for a total of 5,434,780 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (1.163) milliseconds per 271,739 loops.
  • Total difference 23.25 milliseconds for 5,434,780 loops

The iteration variablity for Code 1 was (3.9334) milliseconds and Code 2 was (4.0807) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "foreach", was:

foreach ($GLOBALS['dummy'] as $v)
	$v[0] + 1;

The second test, "for", was:

for ($k = 0, $n = count($GLOBALS['dummy']); $k < $n; $k++)
	$GLOBALS['dummy'][$k][0] + 1;
