Historical ResultsBased on (2) saved test runs, The test labeled "file_exists()" was (on average) the faster by 0.0112 seconds, (1.110% faster)
The file_exists() test took 0.9975 seconds.
The require test took 1.0087 seconds.
Each test case ran 20 random code order iterations consisting of 285,569 loops for a total of 5,711,380 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 285,569 loops.
- Total difference 11.20 milliseconds for 5,711,380 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.
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:
