Encoding utf8 with php

Question

im trying to encode a database in utf8, but nothing work. I think i must change the class functions.php('funciones in spanish'), this is my code:

`<?php
    $link = mysql_connect("localhost", "myvinoalb", "EupN7FNM");
    $dbname = "xxx";
    mysql_select_db($dbname,$link) OR DIE ("Error: Imposible Conectar");
?>`
