有一个数据表student     字段分别是  id name age
                                          字段下值有   1   张三  18 
                                                                 2   李四  17
                                                                 3   王五  18
                                                                 4   李四  17 
我想实现在php里循环输出 table                                               
但是李四的name只输出一次   
                    


                         
                             
                             
                         
                         
                             
                             
                         
                    
名字 年龄
  
想要实现这样的

名字 年龄
张三  18

名字 年龄
李四  17
李四  17

名字 年龄
王五  18

                    $sql=mysql_query('select distinct name from student');
                     while($row=mysql_fetch_array($sql)){
                    
                         
                             
                             
                         
                         
                             
                             
                         
                    
名字 年龄
  
                    }
如果这样写  $row['age'] 获取不到    该怎么实现  php小白  大神麻烦帮忙看一下 谢谢


回复讨论(解决方案)

$sql=mysql_query('select distinct name , age from student');

select distinct name from student
改为
select distinct name,age from student

$sql=mysql_query('select distinct name , age from student');



还有别的方法吗

select distinct name from student
改为
select distinct name,age from student



这种方法行不通   
select *, count(distinct name) from student group by name  这个才能实现  不过还是谢谢
