Result: Discarded

The test labeled "if" was the faster by 0.0068 seconds, (0.869% faster)

if 100%
ternary 99.131%

The if test took 0.7788 seconds.
The ternary test took 0.7857 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 186,932 loops for a total of 3,738,640 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.341) milliseconds per 186,932 loops.
  • Total difference 6.83 milliseconds for 3,738,640 loops

The iteration variablity for Code 1 was (2.9691) milliseconds and Code 2 was (2.5644) 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'] = $GLOBALS['dummy_data'];
	else
		$GLOBALS['dummy'] = 6;
}

The second test, "ternary", was:

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