Historical ResultsBased on (2) saved test runs, The test labeled "file_exists()" was (on average) the faster by 0.0242 seconds, (2.845% faster)
The file_exists() test took 0.8269 seconds.
The require test took 0.8512 seconds.
Each test case ran 20 random code order iterations consisting of 208,754 loops for a total of 4,175,080 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (0.000) milliseconds per 208,754 loops.
- Total difference 24.21 milliseconds for 4,175,080 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:
