$val = array("000","050","100");
$val_name = array("Low","Medium","High");
$count = count($val);
$counter = 0;
while ($counter < $count)
{
        if ($val[$counter] == $priority)
        {
                $selected = " selected";
        }
        echo "<option
value=\"$val[$counter]\"$selected>$val_name[$counter]</option>";
        $counter++;
}
