to array or not to array..

Ok, This is probably a basic question, I am just looking for opinions and examples as to the best way to handle this... I cycling through a query and displaying results to the user such as ... username can add can delete eddie Y N frank N N martha Y Y each of the 'Y's and 'N's represent a checkbox. The user can click checkboxes for several users then click the update button. When they click the update button, I then need to loop through and make updates to the table for each client. What is the best way to handle this? Should these values be put into a multidemensional array keyed off the users id then loop through the array to insert into the table? Should I not use an array and just someone loop through the results? Thanks, Eddie
