multi dimension array

I believe that would be the correct term for what I need. Here is what I have been trying to do. I have orders and customers. Customers are required to do a few things before we can process the order. Some times they are very slow in doing so. So I wanted to write a little reminder script to poke us to email/call them. So I have orders and customers. I need to go through and list out the orders and then I need to use the customer to grab all the order associated with them, then list out their contact information. Anythough on how I can group orders by customer, list the customer information (from another table) and then go on to the next order and so the same thing all over again? ===== -------------------------------------------------------- "Theres no such thing as a problem unless the servers are on fire!" _______________________________ Do you Yahoo!?
