Each test case ran 20 random code order iterations consisting of 142,663 loops for a total of 2,853,260 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.132) milliseconds per 142,663 loops.
  • Total difference 2.63 milliseconds for 2,853,260 loops

The iteration variablity for Code 1 was (7.1037) milliseconds and Code 2 was (8.3889) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "file()", was:

implode('', file('supplement/'));
