Answer 1

没有为您编写代码，您应该能够调整此代码以适应您的需求。

<select name="SELECTNAME"> 
<?php while($rss=mysql_fetch_object($r)) { 
     echo '<option value="' . $value . '" '; 
       if() { // Put your if statement code here for when you want the option to be coloured red. 
        echo 'YOUR RED CLASS'; 
       } 
     echo '>' . $name . '</option>'; 
    } 
?> 
</select>

这就是你想要的东西：

$r=mysql_query("SELECT city.id as city_id,city.city_name,locality.id,locality.area_name ". 
       "FROM city, locality ". 
       "WHERE city.id = locality .city_id order by city_id"); 
$previous = ''; 
?> 
<select name="foo"> 
<?php while($rss=mysql_fetch_object($r)) { ?> 
    <?php if (empty($previous) || $previous != $rss->city_id) { ?> 
     <option name="city[]" style="color:red" value="<?=$rss->city_name?>"><?=$rss->city_name?></option> 
    <?php } ?> 
    <?php $previous = $rss->city_id; ?> 
    <option name="sub_type[]" id="sub_type" value="<?=$rss->id?>"><?=$rss->area_name?></option> 
<?php } ?> 
</select>
