Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 254,586 loops for a total of 5,091,720 runs.

Line execution difference (0.000002) milliseconds.
Avg difference (0.465) milliseconds per 254,586 loops.
Total difference 9.30 milliseconds for 5,091,720 loops

The iteration variablity for Code 1 was (2.4858) milliseconds and Code 2 was (1.7484) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

$result = array();
foreach (new DirectoryIterator($GLOBALS['basedir'] . '/tests') as $file)
{
	if (!$file->isDot())
	    $result[] = $file->getFilename();
}

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

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