Historical Results

Based on (1) saved test runs, The test labeled "error_reporting(0)" was (on average) the faster by 0.0035 seconds, (0.462% faster)

error_reporting(0) 100%
@ (shut up) 99.538%

The error_reporting(0) test took 0.7508 seconds.
The @ (shut up) test took 0.7543 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 192,421 loops for a total of 3,848,420 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 192,421 loops.
  • Total difference 3.49 milliseconds for 3,848,420 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.

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);
