PHP Scandir returns extra periods

Question

So I am trying to build a script that scans a directory and returns random images to be used as backgrounds.

The php looks like this:

$dir = \"views         


        

Answer 1

Why not use regex? That way it captures any amount of periods. (i.e. ".", "..", "..." etc..)

while (false !== ($filename = readdir($dh))) {
        if(!preg_match('/^\.*$/',$filename)){
            $files[] = $filename;
        }
