Answer 1

The actual variable is $_FILES; $_FILES['img'] is a value stored within that array. You can't pass that value to a function and store it in something named $_FILES['img'], but you wouldn't really want to. Name it something like $img, and use that:

function save($img)
{
    $user_file = $img['name'];
    $file_temp = $img['tmp_name'];
    $new = "new/";

    move_uploaded_file($file_temp, $new .$user_file.'');
    echo "<br><b>OK<b>";
}
