如何將SQL查詢的結果轉換為具有特定格式的html表

Question

我正在嘗試為圖書館預訂系統創建一些統計信息。 我的sql查詢的結果看起來像以下結構。

total_no_students| department  | property       | month  
 241             | Physics     | undergraduate  | Nov
 236             | Physics     | undergraduate  | Dec
 254             | Physics     | postgraduate   | Nov
 210             | Physics     | postgraduate   | Dec
 193             | Architecture| undergraduate  | Nov
 181             | Architecture| undergraduate  | Dec
 127             | Architecture| postgraduate   | Nov
 292             | Architecture| postgraduate   | Dec
 134             | Biology     | undergraduate  | Nov
 188             | Biology     | undergraduate  | Dec
 129             | Biology     | postgraduate   | Nov
 219             | Biology     | postgraduate   | Dec

我正在嘗試使用php編寫一些代碼，以創建具有以下外觀的統計信息表：

|Physics-undergrad|Physics-postgrad|Architecture-undergrad|Architecture-postgrad|
Nov |      241        |     254        |         193          |        127          |
Dec |      236        |     210        |         181          |        292          |

對使用php將查詢轉換為上表有幫助嗎？ 非常感謝！

嘗試這個：

SELECT A.month, 
       SUM(CASE WHEN A.department = 'Physics' AND A.property = 'undergraduate' THEN A.total_no_students ELSE 0 END) AS Physics_undergraduate, 
       SUM(CASE WHEN A.department = 'Physics' AND A.property = 'postgraduate' THEN A.total_no_students ELSE 0 END) AS Physics_postgraduate, 
       SUM(CASE WHEN A.department = 'Architecture' AND A.property = 'undergraduate' THEN A.total_no_students ELSE 0 END) AS Architecture_undergraduate, 
       SUM(CASE WHEN A.department = 'Architecture' AND A.property = 'postgraduate' THEN A.total_no_students ELSE 0 END) AS Architecture_postgraduate, 
       SUM(CASE WHEN A.department = 'Biology' AND A.property = 'undergraduate' THEN A.total_no_students ELSE 0 END) AS Biology_undergraduate, 
       SUM(CASE WHEN A.department = 'Biology' AND A.property = 'postgraduate' THEN A.total_no_students ELSE 0 END) AS Biology_postgraduate
FROM (...Your Existing Query...) AS A 
GROUP BY A.month
