Result: DiscardedThe test labeled "function_exists()" was the faster by 0.0091 seconds, (0.848% faster)
The function_exists() test took 1.0583 seconds.
The include_once test took 1.0673 seconds.
Each test case ran 20 random code order iterations consisting of 276,168 loops for a total of 5,523,360 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.453) milliseconds per 276,168 loops.
- Total difference 9.05 milliseconds for 5,523,360 loops
The iteration variablity for Code 1 was (2.9880) milliseconds and Code 2 was (1.6863) 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');
