Result: Discarded

The test labeled "glob(GLOB_NOSORT)" was the faster by 0.0093 seconds, (1.605% faster)

glob(GLOB_NOSORT) 100%
scandir() 98.395%

The glob(GLOB_NOSORT) test took 0.5714 seconds.
The scandir() test took 0.5807 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 142,651 loops for a total of 2,853,020 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.466) milliseconds per 142,651 loops.
  • Total difference 9.32 milliseconds for 2,853,020 loops

The iteration variablity for Code 1 was (2.1239) milliseconds and Code 2 was (2.9822) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "scandir()", was:

clearstatcache();
$result = array();
foreach (scandir($GLOBALS['basedir'] . '/tests') as $file)
{
	if (!is_dir($basedir . '/' . $file))
	{
		$result[] = $file;
	}
}

The second test, "glob(GLOB_NOSORT)", was:

clearstatcache();
$result = array();
foreach (glob($GLOBALS['basedir'] . '/tests/*', GLOB_NOSORT) as $file)
{
	if (!is_dir($file))
	{
		$result[] = $file;
	}
}
