[PHP] an sql_layer

[http://www.promoozz.org [*]]

i'm sweating on this one :

function sql_fetch_row($res, $nr)    
{                                    
global $dbtype;                      
switch ($dbtype) {                   
                                     
    case "MySQL":
        $row = mysql_fetch_row($res);
        return $row;
    break;;
...
}

it iz used in a php_layer.php from phpnuke, but somehow it gives errors... if i put a 
"@" like this:

        $row = @mysql_fetch_row($res);

i get no errors, but no result either. Where stands the @ for? I can't find any info 
on thizz, what's wrong?
