Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 243,430 loops for a total of 4,868,600 runs.

  • Line execution difference (0.000011) milliseconds.
  • Avg difference (2.618) milliseconds per 243,430 loops.
  • Total difference 52.36 milliseconds for 4,868,600 loops

The iteration variablity for Code 1 was (2.3237) milliseconds and Code 2 was (3.3042) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "@ (shut up)", was:

@$GLOBALS['dummy']++;

The second test, "without @", was:

$GLOBALS['dummy']++;
