根據會話結果數量回顯項目

Question

我想根據會話數量從MySQL數據庫中多次取回項目。

例子：

id | qty | item 

    1 | 2 | shoe 

    2 | 4 | net 

    3 | 3 | phone 

我的結果集應該是這樣的：

shoe, shoe 
net, net, net, net 
phone, phone, phone 

我想：

if(isset($_SESSION["cart_products"])) 
    foreach ($_SESSION["cart_products"] as $each_item){ 
     $item_id = $each_item['item_id']; 
    $qty = $each_item['quantity']; 
     $sql = mysql_query("SELECT * FROM products WHERE id='$item_id' ORDER BY id"); 
     $qty = array(); 
    while ($row = mysql_fetch_array($sql)) { 
     $qty[] = $row; 
    }foreach($qty as $row){ 
     $product_name = $row["product_name"]; 
     } 
echo'$product_name'; 

任何幫助表示讚賞。

     $qty = $each_item['quantity'];

       ORDER BY id"); 
     while ($row = mysql_fetch_array($sql)) { 
      $qty = $row['qty']; 
      for($i=0; $i < $qty; $i++){ 
       echo $row['item'].' ';  
      }//end for 
      echo '<br>';//go to next-line  
     }//end while 
}//end foreach
