Question

Why is it when i use scandir using PHP i get extra values

$portID = $this->id;
$dir = '/home/sites/mydomain.com/public_html/public/images/'.$portID;
$contents = scandir($dir);

Is there something i dont know about the function which produces more values than are actually in the folder?

there’s nothing wrong with Pekka’s answer; I’ll just add a more declarative and mockable realization from SPL:

class DirectoryFilterDots extends RecursiveFilterIterator
{
    function __construct($path)
    {
        parent::__construct(new RecursiveDirectoryIterator($path));
    }

    function accept()
    {
        return !$this->getInnerIterator()->isDot();
    }

    function key()
    {
        return $this->getInnerIterator()->getPathname();
    }
}
