Result: Discarded

The test labeled "ternary" was the faster by 0.0454 seconds, (4.179% faster)

ternary 100%
if 95.821%

The ternary test took 1.0407 seconds.
The if test took 1.0861 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 273,690 loops for a total of 5,473,800 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (2.269) milliseconds per 273,690 loops.
  • Total difference 45.39 milliseconds for 5,473,800 loops

The iteration variablity for Code 1 was (7.2277) milliseconds and Code 2 was (2.7981) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "if", was:

for ($i = 0; $i < 100; $i++)
{
	if ($GLOBALS['dummy_true'])
		$GLOBALS['dummy'] = 2;
	else
		$GLOBALS['dummy'] = 6;
}

The second test, "ternary", was:

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = $GLOBALS['dummy_true'] ? 2 : 6;
