[PHP]DirectoryIterator sortowanie wyniku Opcje

[!*!]

Tym sposobem odczytuję listę plików w katalogu, pomijając . oraz .. :

[PHP] pobierz, plaintext 
$directory = 'folder';
 
	foreach (new DirectoryIterator($directory) as $files) {
 
		$onlydirectory = !$files -> isDot() and !$files -> isDir() and !$files -> isExecutable();
		$filename = $files -> getFilename();
		$date = $files -> getMTime();
		$date = date("d-m-Y H:i", $date);		
 
		$size = $files -> getSize();
		$sizeinkb = round($size/1024);
 
		if($onlydirectory) {
 
 
		echo '<tr class="'. $class.'"><td class="tdf"><input type="checkbox" /></td><td class="tdf">'.imagefile($filename).'</td><td class="tdk">'.$filename.'</td><td class="tdn">'.$size.'</td><td class="tdn">'.$date.'</td><td class="tdu">edycja</td><td class="tdu">usun</td></tr>';
 
 
		}
 
	}

Chciałbym nazwy plików posortować alfabetycznie:

[PHP] pobierz, plaintext 
$directory = 'folder';
 
foreach (new DirectoryIterator($directory) as $files) {
 
		$onlydirectory = !$files -> isDot() and !$files -> isDir() and !$files -> isExecutable();
		$filename = $files -> getFilename();
		$date = $files -> getMTime();
		$date = date("d-m-Y H:i", $date);		
 
		$size = $files -> getSize();
		$sizeinkb = round($size/1024);
 
		if($onlydirectory) {
 
 
		$filetab[] = $filename;
 
 
		}
 
	}
sort($filetab);
 
 
foreach ($filetab as $filename) {
echo '<tr class="'. $class.'"><td class="tdf"><input type="checkbox" /></td><td class="tdf">'.imagefile($filename).'</td><td class="tdk">'.$filename.'</td><td class="tdn">'.$sizeinkb.'</td><td class="tdn">'.$date.'</td><td class="tdu">edycja</td><td class="tdu">usun</td></tr>';
 
}
[PHP] pobierz, plaintext 

Jednak nie wiem czy robię to dobrze, oraz jak odczytać w foreach inne dane?

Kod

foreach ($filetab as $filename && )
