php: easy way to compare array

[unwashed potato!]

is there a better way to compare a string against an array other then using foreach...? always felt that although relatively simple this could still be done a lot easier but have never come across another way.

in_array

perfect!

What exactly are you trying to do? See what items are in one but not the other?

pretty much, see if the current id has been shown and if not show it, else continue to next id.
