ptb_merge

Connects to a $filename and "juxtaposes" table from it to the $database (ie. adds its fields). First columns of both tables must be equal (usually it will be ids). If $database is not an array, the other one (being juxtaposed) is returned. If the other (from $filename) isn't, $database is returned.
