Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 244,032 loops for a total of 4,880,640 runs.

Line execution difference (0.000010) milliseconds.
Avg difference (2.562) milliseconds per 244,032 loops.
Total difference 51.23 milliseconds for 4,880,640 loops

The iteration variablity for Code 1 was (2.4153) milliseconds and Code 2 was (2.9056) 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();
