List files in directory but not subdirectories PHP

Question

I have the following code that I am using to list all the files in a specific directory which I then return as JSON

<?php
header('Content-Type: application/json');
$vars = filter_input_array( INPUT_POST, FILTER_SANITIZE_STRING );

$id = $vars['id'];

$dir = $_SERVER['DOCUMENT_ROOT'] . '/resources/' . $id;

$list = array(); //main array

if(is_dir($dir)){
if($dh = opendir($dir)){
    while(($file = readdir($dh)) != false){

        if($file == "." or $file == ".."){
            //...
        } else { //create object with two fields

            array_push($list, $file);
        }
    }
}


echo json_encode($list);
}
?>

However, as well as returning the files, it is also returning a subdirectory that is also in that folder. How do change the if statement to also check whether it is an actual file that has been retrieved?

not your problem, but for correct operation of `readdir` `!= false` should be `!== false` — Nick, Mar 04 '19 at 11:37

Meet is_dir()

if ($file == "." or $file == ".." or is_dir($file)) {
