Historical Results

Based on (1) saved test runs, The test labeled "return code" was (on average) the faster by 0.0332 seconds, (4.743% faster)

return code 100%
Exceptions 95.257%

The return code test took 0.667 seconds.
The Exceptions test took 0.7002 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 132,208 loops for a total of 2,644,160 runs.

  • Line execution difference (0.000013) milliseconds.
  • Avg difference (0.000) milliseconds per 132,208 loops.
  • Total difference 33.21 milliseconds for 2,644,160 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, "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']++;
	}
}
