It appears that you want to extend DB_coomon not DB. The reason is because
$dbh = MyDB::connect( $dsn );
returns an instance of the DB_common class. However, DB_common is the base
class for writing a PEAR DB driver class. And, what is really returned by
DB::connect() is an instance of the driver class that extends DB_comon.
Creating a MyDB_Common will not work either, unless you edit all the DB
database driver class files to extend MyDB_common instead of DB_Common. If
you are doing this for a specific database, then what you should is extend
the corresponding driver class, i.e, mymysql.php. You would then use
'mymysql' instead of 'mysql' as the driver name.
What functionallity do you wish to add to DB?
