MySQL manual (http://dev.mysql.com/doc/refman/5.0/en/create-table.html) states that MySQL does have (limited) support for foreign keys. PHP function mysql_fetch_field (http://www.php.net/manual/en/function.mysql-fetch-field.php) makes it possible to check whether the field is primary_key, unique_key or multiple_key, but we can't check if the field is foreign_key. And, that feature would be most useful...
