Hallo können Sie DirectoryIterator

try {
    $dir = './';
    /* @var $Item DirectoryIterator */
    foreach (new DirectoryIterator($dir) as $Item) {
        if($Item->isFile()) {
            echo $Item->getFilename() . "\n";
        }
    }
} catch (Exception $e) {
    echo 'No files Found!<br />';
}

Wenn Sie übergeben möchten Verzeichnisse rekursiv:
http://php.net/manual/en/class.recursivedirectoryiterator.php

Verwende ich etwas entlang der Linien von:

if ($dir = dir('images'))
{       
    while(false !== ($file = $dir->read()))
    {
        if (!is_dir($file) && $file !== '.' && $file !== '..' && (substr($file, -3) === 'jpg' || substr($file, -3) === 'png' || substr($file, -3) === 'gif'))
        {
            //do stuff with the images
        }
    }
}
else { echo "Could not open directory"; }

$dir = "/etc/php5/";

//Öffnen eines bekannten Verzeichnisses und gehen um den Inhalt zu Lesen

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
        }
        closedir($dh);
    }
}
