Result: Discarded
The test labeled "require" was the faster by 0.0362 seconds, (2.929% faster)
The require test took 1.1995 seconds.
The file_exists() test took 1.2357 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 290,564 loops for a total of 5,811,280 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (1.810) milliseconds per 290,564 loops.
- Total difference 36.20 milliseconds for 5,811,280 loops
The iteration variablity for Code 1 was (12.7904) milliseconds and Code 2 was (11.5424) 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');
