Each test case ran 20 random code order iterations consisting of 142,590 loops for a total of 2,851,800 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.674) milliseconds per 142,590 loops.
  • Total difference 13.47 milliseconds for 2,851,800 loops

The iteration variablity for Code 1 was (2.5700) milliseconds and Code 2 was (1.9502) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "echo", was:

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

The second test, "<?php ?>", was:
