Result: DiscardedThe test labeled "include_once" was the faster by 0.0027 seconds, (0.253% faster)
The include_once test took 1.0783 seconds.
The function_exists() test took 1.0811 seconds.
Each test case ran 20 random code order iterations consisting of 283,351 loops for a total of 5,667,020 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.137) milliseconds per 283,351 loops.
- Total difference 2.74 milliseconds for 5,667,020 loops
The iteration variablity for Code 1 was (6.4389) milliseconds and Code 2 was (5.4330) 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');
