Based on (4) saved test runs, The test labeled "@ (shut up)" was (on average) the faster by 0.0195 seconds, (2.417% faster)

@ (shut up) 100%
error_reporting(0) 97.583%

The @ (shut up) test took 0.7872 seconds.
The error_reporting(0) test took 0.8067 seconds.


Each test case ran 20 random code order iterations consisting of 191,503 loops for a total of 3,830,065 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.000) milliseconds per 191,503 loops.
  • Total difference 19.50 milliseconds for 3,830,065 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, "@ (shut up)", was:

$temp = 0;
$GLOBALS['dummy'] = $temp;

The second test, "error_reporting(0)", was:

$temp = error_reporting(0);
