Result: Discarded
The test labeled "file_exists()" was the faster by 0.0363 seconds, (6.073% faster)
The file_exists() test took 0.5608 seconds.
The require test took 0.597 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 135,420 loops for a total of 2,708,400 runs.
- Line execution difference (0.000013) milliseconds.
- Avg difference (1.813) milliseconds per 135,420 loops.
- Total difference 36.26 milliseconds for 2,708,400 loops
The iteration variablity for Code 1 was (3.7512) milliseconds and Code 2 was (4.4344) 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');
