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.

yes, in_array($person, $people)!

however, you may take a look into the manual.
