RE: [PHP] array search

Joseph, The below postings are what you're looking for. Hopefully the in_array PHP function uses a smart search algorithm and doesn't go through the entire array. If you store your values in a db you can make use of an index on the column, or you could write your own search algorithm that uses a btree or some other type of search methodology.
