PHP Return not working in Kohana

Question

I tried running the following code and it supposed to pick the value from the database but not picking.

            $val = doautocomp('Brisbane');

        HTTP::redirect($url_address.'/hotel-search/go/' . $val);
        exit;
    }
    else {
        HTTP::redirect($url_address.'/hotel-search/error');
        exit;
    }
}
function seoUrl($string) {
        $string = strtolower($string);
        $string = preg_replace("/[^a-z0-9_\s-]/", "", $string);
        $string = preg_replace("/[\s-]+/", " ", $string);
        $string = preg_replace("/[\s_]/", "-", $string);
        return $string;
}
function doautocomp($mval) {
    $linker = mysql_connect('localhost', 'root', 'pass');
    $result3 = mysql_query("SELECT name FROM the.autocompletes where name LIKE '".$mval."%' LIMIT 0,1");
    while($row = mysql_fetch_array($result3))
      {
          $val1 = $row['name'];
          $mval = seoUrl($val1);

      }
      return $mval;
      mysql_close($linker);
}  

I also tried as but still its not working. RETURN TEST

        $val = doautocomp('Brisbane');

        HTTP::redirect($url_address.'/hotel-search/go/' . $val);
        exit;
    }
    else {
        HTTP::redirect($url_address.'/hotel-search/error');
        exit;
    }
}
function seoUrl($string) {
        $string = strtolower($string);
        $string = preg_replace("/[^a-z0-9_\s-]/", "", $string);
        $string = preg_replace("/[\s-]+/", " ", $string);
        $string = preg_replace("/[\s_]/", "-", $string);
        return $string;
}
function doautocomp($mval) {
    $linker = mysql_connect('localhost', 'root', 'pass');
    $result3 = mysql_query("SELECT name FROM the.autocompletes where name LIKE '".$mval."%' LIMIT 0,1");
    while($row = mysql_fetch_array($result3))
      {
          $val1 = $row['name'];
          $mval = seoUrl($val1);

      }
      return "test"; //$mval;
      mysql_close($linker);
}

I have some problems understanding your code right. You are using a framework with a good database class. Why do you use "mysql_connect". Your "mysql_close()" comes under the "return" statement. So maybe your last connection isn't closed right. Did you try a return "TEST" before mysql is used?

You should write your code more like this:

function doautocomp($mval) {

    $row = Database::instance()->query(Database::SELECT,
        DB::select('name')
            ->from('autocompletes')
            ->where('name','LIKE',$mval.'%')
            ->limit(1)
        )->current();

    if ($row === FALSE)
    {
        return "";
    }

    $val1 = $row['name'];
    $mval = seoUrl($val1);

    return $mval;
}
