The require test took 1.1425 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 275,759 loops for a total of 5,515,180 runs.
- Line execution difference (0.000016) milliseconds.
- Avg difference (4.397) milliseconds per 275,759 loops.
- Total difference 87.94 milliseconds for 5,515,180 loops
The iteration variablity for Code 1 was (3.3715) milliseconds and Code 2 was (5.4892) 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');
