I have the folowing function:

    function renewloc ($lset,&$l,&$ld) {
        $db = mysql_connect();
        mysql_select_db("cefac",$db);
        $sqls = "SELECT locid,locnome FROM locais ORDER BY locid";
        $result = mysql_query($sqls,$db);
        $row = mysql_fetch_row($result);
        if ($lset)
        {
            $l = $row[0];
            $ld = $row[1];
        }
        $larr = '';
        do {
            $larr = $larr . $row[0] . "|" . $row[1] . "@";
        } while ($row = mysql_fetch_row($result));
        mysql_close($db);
        return substr($larr,0,strlen($larr)-1);
    }

The function works well, set the referenced variables and returns a result. Within the page from which the function was called I can play with the result, but if I set a session variable with this result, the session file is written with this value as an integer with value 0;

If I use the following code:

       include('funct.inc');
       $myvar = renewloc(true,$mg_loc,$mg_locd);

where 'funct.inc' is the include page where I have the renewloc function defined, $tmp has the right value as soon as the function returns, but now look at this code:

       session_register('myvar');
       session_register('mytest');
       include('funct.inc');
       $myvar = renewloc(true,$mg_loc,$mg_locd);
       $mytest = 'testing';

myvar has the right value, but on the next page, only the mytest value is held. myvar is written as an integer value that contains 0.

If I substitue the function by its code directly on the page everything works fine. Maybe this is a problem inserted on the last changes of referencing variables.
