What is the potential issue with uploading larger files outside of the document root in PHP?

When uploading larger files outside of the document root in PHP, it can potentially pose a security risk as it allows users to upload files that can be executed on the server. To solve this issue, it is recommended to store uploaded files in a separate directory outside of the document root and use a script to serve the files to users securely. 

<?php
// Define the directory to store uploaded files
$uploadDir = '/path/to/uploaded/files/';

// Check if the file has been uploaded
if(isset($_FILES['uploaded_file'])) {
    $file = $_FILES['uploaded_file'];

    // Move the uploaded file to the designated directory
    move_uploaded_file($file['tmp_name'], $uploadDir . $file['name']);
}
?>
