Historical Results

Based on (2) saved test runs, The test labeled "@ (shut up)" was (on average) the faster by 0.0009 seconds, (0.100% faster)

@ (shut up) 100%
error_reporting(0) 99.9%

The @ (shut up) test took 0.946 seconds.
The error_reporting(0) test took 0.9469 seconds.


Each test case ran 20 random code order iterations consisting of 240,543 loops for a total of 4,810,860 runs.

  • Line execution difference (0.000000) milliseconds.
  • Avg difference (0.000) milliseconds per 240,543 loops.
  • Total difference 0.95 milliseconds for 4,810,860 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);
