Result: SavedThe test labeled "non-referenced" was the faster by 0.0082 seconds, (1.523% faster)
The non-referenced test took 0.5298 seconds.
The referenced test took 0.538 seconds.
Each test case ran 20 random code order iterations consisting of 117,751 loops for a total of 2,355,020 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.410) milliseconds per 117,751 loops.
- Total difference 8.19 milliseconds for 2,355,020 loops
The iteration variablity for Code 1 was (1.6656) milliseconds and Code 2 was (1.7353) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "non-referenced", was:
foreach ($GLOBALS['dummy'] as $k => $v) $v++; unset($v);
The second test, "referenced", was:
foreach ($GLOBALS['dummy'] as $k => &$v) $v++; unset($v);
