Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 140,571 loops for a total of 2,811,420 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.497) milliseconds per 140,571 loops.
  • Total difference 9.95 milliseconds for 2,811,420 loops

The iteration variablity for Code 1 was (2.1341) milliseconds and Code 2 was (2.9747) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "echo", was:

echo $GLOBALS['x'], ' test ', $GLOBALS['y'], $GLOBALS['z'], ' test ';
