Historical ResultsBased on (4) saved test runs, The test labeled "include_once" was (on average) the faster by 0.0136 seconds, (1.795% faster)
The include_once test took 0.7416 seconds.
The function_exists() test took 0.7552 seconds.
Each test case ran 20 random code order iterations consisting of 191,557 loops for a total of 3,831,140 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 191,557 loops.
- Total difference 13.55 milliseconds for 3,831,140 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, "include_once", was:
The second test, "function_exists()", was:
clearstatcache(); if (!function_exists('f2')) include('supplement/func2.inc');
