urgent question

Dear sir, i am very new to php, i need to display some credit card numbers from a database, how is that done? Batch: 1.. Display number of used Cashlink and Others cards 2.. Display the mobile phone number next to the provider field 3.. Order list by mobile phone numbers 4.. Display the number of clients who bought more than one card during the selected date range Invoice: 1.. Instead of having a list box of the clients, use an enter field, in which a mobile number can be entered 2.. Add date range selection fields, during which the client has bought cards 3.. Retrieve from the db the number of cards the user bought in that date period, and calculate the receipt amount Referrals: 1.. Display the name of the referral person 2.. Add an extra field which shows if the referral person has received a free voucher Edit mobile no: 1.. Add the function of searching the details of a client by entering his mobile number i wouldn't mind if the examples are generic as long as i know where 2 start thanking u for ur kind co-operation regards Naomi
