Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 195,995 loops for a total of 3,919,900 runs.

Line execution difference (0.000005) milliseconds.
Avg difference (0.951) milliseconds per 195,995 loops.
Total difference 19.01 milliseconds for 3,919,900 loops

The iteration variablity for Code 1 was (0.4709) milliseconds and Code 2 was (0.4390) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "return code", was:

for ($i = 0; $i < 100; $i++)
{
	if (return_false() === false)
		$GLOBALS['dummy']++;
}

The second test, "Exceptions", was:

for ($i = 0; $i < 100; $i++)
{
	try
	{
		throw_exception();
	}
	catch (Exception $e)
	{
		$GLOBALS['dummy']++;
	}
}
