Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 228,581 loops for a total of 4,571,616 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 228,581 loops.
  • Total difference 14.65 milliseconds for 4,571,616 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, "if elseif else", was:

foreach ($GLOBALS['dummy'] as $v)
{
	if ($v == 2)
		$GLOBALS['dummy2'] = 1;
	elseif ($v == 5)
		$GLOBALS['dummy2'] = 2;
	elseif ($v == 1)
		$GLOBALS['dummy2'] = 3;
	elseif ($v == 3)
		$GLOBALS['dummy2'] = 4;
	elseif ($v == 0)
		$GLOBALS['dummy2'] = 5;
	else
		$GLOBALS['dummy2'] = 6;
}

The second test, "switch", was:

foreach ($GLOBALS['dummy'] as $v)
{
	switch ($v)
	{
	case 2:
		$GLOBALS['dummy2'] = 1;
		break;

	case 5:
		$GLOBALS['dummy2'] = 2;
		break;

	case 1:
		$GLOBALS['dummy2'] = 3;
		break;

	case 3:
		$GLOBALS['dummy2'] = 4;
		break;

	case 0:
		$GLOBALS['dummy2'] = 5;
		break;

	default:
		$GLOBALS['dummy2'] = 6;
	}
}
