Result: DiscardedThe test labeled "include_once" was the faster by 0.0097 seconds, (1.771% faster)
The include_once test took 0.5376 seconds.
The function_exists() test took 0.5473 seconds.
Each test case ran 20 random code order iterations consisting of 142,518 loops for a total of 2,850,360 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.485) milliseconds per 142,518 loops.
- Total difference 9.69 milliseconds for 2,850,360 loops
The iteration variablity for Code 1 was (1.9470) milliseconds and Code 2 was (2.6041) 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');
