Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 228,354 loops for a total of 4,567,080 runs.

Line execution difference (0.000011) milliseconds.
Avg difference (2.488) milliseconds per 228,354 loops.
Total difference 49.77 milliseconds for 4,567,080 loops

The iteration variablity for Code 1 was (3.0040) milliseconds and Code 2 was (3.6215) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

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

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;
	}
}
