The ternary test took 0.6344 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 138,140 loops for a total of 2,762,800 runs.

Line execution difference (0.000019) milliseconds.
Avg difference (2.683) milliseconds per 138,140 loops.
Total difference 53.66 milliseconds for 2,762,800 loops

The iteration variablity for Code 1 was (5.6175) milliseconds and Code 2 was (7.9237) 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;
