php选择选项名称和值

Question

这是我的编码

$sql="SELECT code,rate, name FROM price_detail WHERE ref_no='VACC'"; 

echo "<select   onchange='vaccines(this)' name='student' value='0'><option> Select Vaccines Type</option>";

foreach ($dbh->query($sql) as $row){
            echo "<option value=$row[rate]>$row[name]</option>"; 
                    }
echo "</select>";

这里我需要$ row ['name'] 对于$ row ['rate']我取选项的值 我怎么能回复['name']
