Result: Discarded
The test labeled "include_once" was the faster by 0.0066 seconds, (0.893% faster)
The include_once test took 0.7327 seconds.
The function_exists() test took 0.7393 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 177,349 loops for a total of 3,546,980 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.330) milliseconds per 177,349 loops.
- Total difference 6.60 milliseconds for 3,546,980 loops
The iteration variablity for Code 1 was (5.3267) milliseconds and Code 2 was (6.8336) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "include_once", was:
clearstatcache();
include_once('supplement/func1.inc');
The second test, "function_exists()", was:
clearstatcache();
if (!function_exists('f2'))
include('supplement/func2.inc');
