Result: DiscardedThe test labeled "include_once" was the faster by 0.1051 seconds, (8.645% faster)
The include_once test took 1.1107 seconds.
The function_exists() test took 1.2158 seconds.
Each test case ran 20 random code order iterations consisting of 282,254 loops for a total of 5,645,080 runs.
- Line execution difference (0.000019) milliseconds.
- Avg difference (5.255) milliseconds per 282,254 loops.
- Total difference 105.10 milliseconds for 5,645,080 loops
The iteration variablity for Code 1 was (6.6346) milliseconds and Code 2 was (10.8137) 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');
