Historical Results

Based on (1) saved test runs, The test labeled "if" was (on average) the faster by 0.0093 seconds, (0.947% faster)

if 100%
ternary 99.053%

The if test took 0.9764 seconds.
The ternary test took 0.9858 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 276,213 loops for a total of 5,524,260 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 276,213 loops.
  • Total difference 9.34 milliseconds for 5,524,260 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", 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;
