如何使用PHP和mysql在xls文件中打印值而不是id

Question

我使用PHP Mysql.i提交表單並將數據提取到我的page.For表格中的表格格式現在我希望用戶可以下載xls文件從該表，但我的問題是，在我的數據庫表幾個值是在ID形式我怎麼能檢索他們在XLS文件因爲在XLS文件它顯示ID的，因爲有在數據庫表中的ID我不想提交值名稱可以名稱可以不止一個。

這裏是我的下載XLS鏈接代碼：

<span style="float:right;"><a href="customer_xls.php" type="button" class="btn">Download XLS</a></span> 

這裏是customer_xls.php文件：

你必須使用表格加入您的基本表，其中包含的單詞表示編號保存在第一個表格中。例如：

Table A: 
id | id_user | id_city 
1 | 10  | 5 

Table B: 
id | user_name 
10 | Michael 

Table C: 
id | city_name 
5 | New York 

對於表，你應該建立這樣的查詢：

SELECT a.id, b.user_name, c.city_name FROM table_a a 
JOIN table_b b ON a.id_user = b.id JOIN 
JOIN table_c c ON a.id_city = c.id 

該查詢的結果應該是這樣的：

1 | Michael | New York 

其他方式得到相同的結果是構建子查詢（但比JOIN方法更耗時）。例如：

SELECT id, (SELECT user_name FROM table_b WHERE id = a.id_user) name, 
(SELECT city_name FROM table_c WHERE id = a.id_city) city FROM table_a a
