How iterate through controls in a form?

[sexycollegeboy]

I'm pretty new to PHP and I'm currently working on my first PHP website. I have a need to display (and add/edit) rows in a table in a single form.What I'm going for is a row in the form for each row in the table plus one blank row so the user can add more items into the table.When they click the save button I want all the existing rows to update and the new row (if data present) to insert.Is there an easy way I can iterate through all the controls in a form or something of the sort?Thanks in advance,Sonny
