readdir only gives dots - php

Question

So, I have this function and for some reason, it only returns dots, while anywhere else it returns what it should

function scan($dir){
    $open = opendir($dir);
    $Name = readdir($open);
    return $Name;
}

scan('/home/user/scan/scan-test2');

I used the exact same way of opening directories in another function and for some reason there it reads everything that is inside scan-test2.

In scan-test2 there is a folder with 4 text files in it

Why not use [scandir](http://php.net/manual/en/function.scandir.php) — IsThisJavascript, Jan 18 '18 at 10:32
@IsThisJavascript scandir returns nothing or NULL with the warning " scandir() expects parameter 1 to be a valid path, resource given" — SoManyQuestions, Jan 18 '18 at 10:34
It sounds like you're passing the result of `opendir` into `scandir` - you just need to provide the path. `readdir` only returns a single entry from a directory with each call, which is why this won't be working. — iainn, Jan 18 '18 at 10:37
Your function only ever returns the first entry found in any case ... You need a _loop_ if you want all entries. — CBroe, Jan 18 '18 at 10:38

Use the scandir() PHP's function as this:

$files = scandir($path);
unset($files[0]); // remove .
unset($files[1]); // remove ..
