The test labeled "fcall" was the faster by 0.0084 seconds, (0.948% faster)

fcall 100%
no fcall 99.052%

The fcall test took 0.8768 seconds.
The no fcall test took 0.8851 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 231,985 loops for a total of 4,639,700 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.419) milliseconds per 231,985 loops.
  • Total difference 8.39 milliseconds for 4,639,700 loops

The iteration variablity for Code 1 was (1.4813) milliseconds and Code 2 was (1.4166) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "fcall", was:

/*
function do_something()
{
	for ($i = 0; $i < 20; $i++)
		$GLOBALS['dummy'] + $i;
}
*/

do_something();

The second test, "no fcall", was:

for ($i = 0; $i < 20; $i++)
	$GLOBALS['dummy'] + $i;
