根据包显示产品

Question

我想根据其包显示对象（item）。使用我现在的PHP代码，我得到了这样的结果：

    ----------------------------------------------------------------------
    Package           Price            Deskription        Prodcut    
    ----------------------------------------------------------------------
   => 2kg             20                sdasdsada          
   => 4kg             40                sdasdsada         PRODCUT ONE 
   => 6kg             60                sdasdsada          
   => 8kg             80                sdasdsada          
    ----------------------------------------------------------------------
   => 2kg             20                sdasdsada          
   => 4kg             40                sdasdsada         PRODCUT TWO 
   => 6kg             60                sdasdsada          
   => 8kg             80                sdasdsada          

=>是一个下拉列表

然而，我想要的结果是这样的：

    ----------------------------------------------------------------------
    Package           Price            Deskription        Etc    
    ----------------------------------------------------------------------
                      20                sdasdsada         
   => 2,4,6,8kg       40                sdasdsada         PRODCUT ONE 
                      60                sdasdsada         
                      80                sdasdsada         
    ----------------------------------------------------------------------
                      20                sdasdsada         
   => 2,4,6,8kg       40                sdasdsada         PRODCUT TWO 
                      60                sdasdsada         
                      80                sdasdsada
