Delete from Multidimensional Array?

I think I've outsmarted myself, again. Can someone help me out of this, please? I've built a page that collects network card information, assigning each element its place within a $Card array, and all of the cards to $NetCards. As you enter your card information at the bottom, the previous card is displayed above it, with a Delete checkbox option at the end of that row ($Delete[$Card]). But I can't figure out how to actually delete that card from the "deck", as it were. I've looked over the Arrays pages, but there's little there about multi-dimensional arrays and I ended up more confused than ever. Here's my print_r: Array <=--- This is $NetCards ( [0] => Array <=--- This one is just $Card ( [0] => 3Com <=--- Description [1] => 12:34:45:78:90:AA <=--- MAC Address [2] => 129.93.100.100 <=--- IP Address ) [1] => Array ( [0] => Intel 100b [1] => 12:34:45:78:90:AB [2] => 129.93.100.101 ) [2] => Array ( [0] => ThinAire [1] => 12:34:45:78:90:BB [2] => 129.93.100.102 ) [3] => Array ( [0] => 3Com [1] => 12:34:45:78:90:BC [2] => 129.93.100.103 ) ) How can I delete, say, the wireless card (ThinAire) which is third, here, if someone clicks on that one's Delete box?
