Historical ResultsBased on (3) saved test runs, The test labeled "function_exists()" was (on average) the faster by 0.0004 seconds, (0.057% faster)
The function_exists() test took 0.7532 seconds.
The include_once test took 0.7536 seconds.
Each test case ran 20 random code order iterations consisting of 179,529 loops for a total of 3,590,587 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.000) milliseconds per 179,529 loops.
- Total difference 0.43 milliseconds for 3,590,587 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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');
