php - 获取开始日期到结束日期之间的日期，以 php 月份明智计数

Question

在 php 中如何按月按月计算以下数据中的每个用户

SELECT * FROM sales_info WHERE assigned_dse_name IN ('ANBHAZHAGAN .') AND invoice_date BETWEEN '2016-01-01 00:00:00' AND '2016-06-01 23:59:59'

在想取数有

 month   count
  01      0
  02      0
  03      5
  04      3
  05      7
  06      4

如何使用拆分月份明智循环进行查询。

试试这个；)

SELECT `mouth`, sum(`count`) AS `count` 
FROM (
    SELECT LPAD(MONTH(invoice_date), 2, '0') AS `month`, COUNT(1) as `count`
    FROM sales_info
    WHERE assigned_dse_name IN ('ANBHAZHAGAN .') AND invoice_date BETWEEN '2016-01-01 00:00:00' AND '2016-06-01 23:59:59'
    GROUP BY MONTH(invoice_date)
    UNION
    SELECT LPAD(t.`month`, 2, '0') AS `month`, t.`count` FROM (
        SELECT 1 AS `month`, 0 AS `count` UNION
        SELECT 2 AS `month`, 0 AS `count` UNION
        SELECT 3 AS `month`, 0 AS `count` UNION
        SELECT 4 AS `month`, 0 AS `count` UNION
        SELECT 5 AS `month`, 0 AS `count` UNION
        SELECT 6 AS `month`, 0 AS `count` UNION
        SELECT 7 AS `month`, 0 AS `count` UNION
        SELECT 8 AS `month`, 0 AS `count` UNION
        SELECT 9 AS `month`, 0 AS `count` UNION
        SELECT 10 AS `month`, 0 AS `count` UNION
        SELECT 11 AS `month`, 0 AS `count` UNION
        SELECT 12 AS `month`, 0 AS `count`) t
    WHERE t.`month` >= MONTH('2016-01-01 00:00:00') AND t.`month` <= MONTH('2016-06-01 23:59:59'))TMP
GROUP BY `month`
ORDER BY `month`
