Question

I want to know how to display report by month using PHP and Mysql

Example of Report on the web page:

January 2011
==============
Store  Name    |  Total Order Cost
SHOP A         |  £123 
SHOP B         |  £100

February 2011
==============
Store  Name    |  Total Order Cost
SHOP A         |  £123 
SHOP B         |  £100
SHOP C         |  £99.40

I have mysql tables

tbl_shop

• ShopID

• ShopName

tbl_order

• OrderID

• ShopID

• OrderDate

• Total

Answer 1

You will need to iterate trough the result of the query and create an multidimensional array using the month/year combination as keys. The query below should be a good indication on how to fetch the required information from your database.

SELECT 
    MONTH(to.OrderDate), 
    YEAR(to.OrderDate), 
    SUM(to.Total), 
    to.* 
FROM tbl_order as to
INNER JOIN tbl_shop as ts ON ts.ShopID = to.ShopID
GROUP BY to.ShopID, MONTH(to.OrderDate), YEAR(to.OrderDate)

Note that I havn’t tested this query – please handle it as pseudo-code. You might need to throw around the GROUP BY fields a little and test if it works.
