Getting user id in a php file

[Dadparvar]

Hi,

In a php file, where there is upload process (not related to xenforo's upload process) I have this code:

    if(move_uploaded_file($_FILES['upl']['tmp_name'], 'uploads/'.$_FILES['upl']['name'])){
        echo '{"status":"success"}';
        exit;
    }

That will cause the file be uploaded in "uploads" folder.
How to change it, so that when user with user_id 1 upload the file, then it be uploaded in folder "1" and if user 2 did, then in "2" and so...

I tested this code, bu now worked:

  $user = XenForo_Visitor::getInstance()->toArray();
  $userId = $user['user_id'];

    if(move_uploaded_file($_FILES['upl']['tmp_name'], $userId.'/'.$_FILES['upl']['name'])){
        echo '{"status":"success"}';
        exit;
    }

Thanks in advance

Also this is the codes I used in template to connect to this php file to add the upload box to a page:

<xen:require css="dadparvar_profilemusic_uploader.css" />
<form id="upload" method="post" action="styles/default/dadparvar/profilemusic/songs/upload.php" enctype="multipart/form-data">
            <div id="drop">
                Drop Here

                <a>Browse</a>
                <input type="file" name="upl" multiple />
            </div>

            <ul>
                <!-- The file uploads will be shown here -->
            </ul>

</form>
