Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 175,449 loops for a total of 3,508,975 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 175,449 loops.
  • Total difference 4.35 milliseconds for 3,508,975 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, "multiply", was:

$GLOBALS['dummy'] = 0;
for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy'] = $GLOBALS['dummy_int'] * 2;

The second test, "add", was:

$GLOBALS['dummy'] = 0;
for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy'] = $GLOBALS['dummy_int'] + $GLOBALS['dummy_int'];
