Result: DiscardedThe test labeled "include_once" was the faster by 0.0046 seconds, (0.688% faster)
The include_once test took 0.6578 seconds.
The function_exists() test took 0.6623 seconds.
Each test case ran 20 random code order iterations consisting of 130,379 loops for a total of 2,607,580 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.228) milliseconds per 130,379 loops.
- Total difference 4.55 milliseconds for 2,607,580 loops
The iteration variablity for Code 1 was (9.2748) milliseconds and Code 2 was (9.5564) 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');
