You need a better SQL statement to select patients and dates where this
condition exists. Don't do this in PHP, do it in Mysql.

Sadly my SQL is only good enough to know that this *can* be done, and
simply. It would take me hours to get the SQL query right, but
comp.databases.mysql is that way==>

Assuming you are in fact querying a database to get your arrays.

If not you bloody well should be :-)
