这是代码

        $get_favory = mysql_query("SELECT * FROM favory WHERE user1='$username'");

        $values = "";

        while($fav = mysql_fetch_assoc($get_favory)) {
        $user2 = $fav['user2'];
        $values = " OR added_by='".$user2."'";
        }

        echo $values;

值变量必须是这样的：OR added_by='zac' OR linked_by='john' OR linked_by='emily'
但我得到这个结果：OR linked_by='zac'

我必须做什么？
