order of elements in $_POST super global

Hello All, I'm using a form (method="POST") to collect 30 boolean values from the end user using a series of checkboxes in the form. The form is arranged in a table so that the 30 check boxes are not a long list but rather three columns (with related items columnized). The problem is when I iterate through the $_POST results: The order in which I wish to present the checkboxes to the end user is different than the order I want to have in the $_POST super global and subsequently when I dump that information out to a text file. What would be the best way to solve this? 1) Is there a way to present the checkboxes in a certain order, yet have the data transmitted into the $_POST super global in a different order? 2) Does it make more sense to process the $_POST super global array and reorder the items within the array? 3) Some other method? Thanks for any advice. - Ben
