Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 208,076 loops for a total of 4,161,520 runs.

Line execution difference (0.000002) milliseconds.
Avg difference (0.493) milliseconds per 208,076 loops.
Total difference 9.86 milliseconds for 4,161,520 loops

The iteration variablity for Code 1 was (1.5087) milliseconds and Code 2 was (0.9104) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "file_exists()", was:

clearstatcache();

if (!file_exists('supplement/dummy.inc'))
	trigger_error('Required file not found!', E_USER_ERROR);
include('supplement/dummy.inc');

The second test, "require", was:

clearstatcache();
require('supplement/dummy.inc');
