如何在php中查找按月过滤的总金额？

我试图在报告表中找到

报告状态

的总金额，但我不知道如何找到。我只能计算报告状态的

，但不能按月计算

$count = "SELECT 
(SELECT COUNT(REPORT_STATUS) FROM REPORT WHERE REPORT_STATUS = 1 ) as 
NumberOfReport1, (SELECT COUNT(REPORT_STATUS)  FROM REPORT WHERE REPORT_STATUS = 2) 
as NumberOfAReport2,(SELECT COUNT(REPORT_STATUS)  FROM REPORT WHERE REPORT_STATUS = 3) 
as NumberOfReport3,(SELECT COUNT(REPORT_STATUS)  FROM REPORT WHERE REPORT_STATUS = 4) 
as NumberOfReport4 ";

$result1= mysql_query($count);

他是你的朋友。大概是这样的：

SELECT month, COUNT(REPORT_STATUS) FROM REPORT WHERE REPORT_STATUS = 1 GROUP BY month

看看这个也许你还不能做什么？结果是什么？你想要什么？有错误吗。。。请回答你的问题。
