I have a code like this below, which gives me a $link that equals to: http://mydomain.com/image/photo.JPG

if (!empty($_SESSION['item'][$i]))
{
    $path = dirname(__FILE__).'/image/'.basename($_SESSION['item'][$i]);
    if (move_uploaded_file($_SESSION['item'][$i], $path)) 
        global $url;

    if ( $url )
    {
        $link = $url.'/image/'.basename($_SESSION['item'][$i]);
        echo "<td><img src='" . $link . "' width='50' height='50' /></td>";
    }
}

I wonder, how should I properly ommit using global variable here to achieve the same result.
