Result: Discarded
The test labeled "@ (shut up)" was the faster by 0.0476 seconds, (4.396% faster)
The @ (shut up) test took 1.0358 seconds.
The error_reporting(0) test took 1.0834 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 289,511 loops for a total of 5,790,220 runs.
- Line execution difference (0.000008) milliseconds.
- Avg difference (2.381) milliseconds per 289,511 loops.
- Total difference 47.63 milliseconds for 5,790,220 loops
The iteration variablity for Code 1 was (2.2023) milliseconds and Code 2 was (4.3723) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "@ (shut up)", was:
$temp = 0; @$GLOBALS[dummy]++; $GLOBALS['dummy'] = $temp;
The second test, "error_reporting(0)", was:
$temp = error_reporting(0); $GLOBALS[dummy]++; error_reporting($temp);
