Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 134,702 loops for a total of 2,694,040 runs.

  • Line execution difference (0.000012) milliseconds.
  • Avg difference (1.597) milliseconds per 134,702 loops.
  • Total difference 31.93 milliseconds for 2,694,040 loops

The iteration variablity for Code 1 was (1.2213) milliseconds and Code 2 was (1.4756) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "else if", was:

if ($GLOBALS['dummy_false'])
	$GLOBALS['dummy_false'] = true;
else if ($GLOBALS['dummy_true'])
	$GLOBALS['dummy_true'] = true;

The second test, "elseif", was:

if ($GLOBALS['dummy_false'])
	$GLOBALS['dummy_false'] = true;
elseif ($GLOBALS['dummy_true'])
	$GLOBALS['dummy_true'] = true;
