Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 288,714 loops for a total of 5,774,280 runs.
- Line execution difference (0.000009) milliseconds.
- Avg difference (2.465) milliseconds per 288,714 loops.
- Total difference 49.29 milliseconds for 5,774,280 loops
The iteration variablity for Code 1 was (7.2697) milliseconds and Code 2 was (10.7814) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "multiply", was:
$GLOBALS['dummy'] = 0; for ($j = 0; $j < 100; $j++) $GLOBALS['dummy'] = $GLOBALS['dummy_int'] * 2;
The second test, "add", was:
$GLOBALS['dummy'] = 0; for ($j = 0; $j < 100; $j++) $GLOBALS['dummy'] = $GLOBALS['dummy_int'] + $GLOBALS['dummy_int'];
