This may be some sort of weird longer shortcut, and please correct me if I'm mistaken in this train of thought...

I have a matrix of data that looks like:

unique_id | URL | other random data...
unique_id | URL | other random data...
unique_id | URL | other random data...

I want to be able to reference an item by either its URL, or its unique_id. Is there a fancy way to do this?

I suppose the cheating solution would be to just make two arrays, but is there is a better way?

php arrays multidimensional-array
