Result: DiscardedThe test labeled "include_once" was the faster by 0.0661 seconds, (7.385% faster)
The include_once test took 0.8285 seconds.
The function_exists() test took 0.8946 seconds.
Each test case ran 20 random code order iterations consisting of 213,559 loops for a total of 4,271,180 runs.
- Line execution difference (0.000015) milliseconds.
- Avg difference (3.303) milliseconds per 213,559 loops.
- Total difference 66.07 milliseconds for 4,271,180 loops
The iteration variablity for Code 1 was (2.1913) milliseconds and Code 2 was (5.6439) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "include_once", was:
The second test, "function_exists()", was:
clearstatcache(); if (!function_exists('f2')) include('supplement/func2.inc');
