Listing all Files in a Directory

<?php

function numfilesindir ($dir){
    //First, we ensure that the directory exists.
    if (is_dir ($dir)){
        //Now, we scan the files in this
        //directory using scandir.
        $scanarray = scandir ($dir);
        //Then we begin parsing the array.
        //Since scandir() counts the "." and ".."
        //file navigation listings
        //as files, we should not list them.
        for ($i = 0; $i < count ($scanarray); $i++){

                //and not a directory.
