[line 188]

The main 'MDB' class is simply a container class with some static  methods for creating DB objects as well as some utility functions  common to all parts of DB.
The object model of DB is as follows (indentation means inheritance):
MDB          The main DB class.  This is simply a utility class               with some 'static' methods for creating MDB objects as               well as common utility functions for other MDB classes.
MDB_common   The base for each DB implementation.  Provides default  |            implementations (in OO lingo virtual methods) for  |            the actual DB implementations as well as a bunch of  |            query utility functions.  |  +-MDB_mysql  The DB implementation for MySQL. Inherits MDB_Common.               When calling MDB::factory or MDB::connect for MySQL               connections, the object returned is an instance of this               class.  +-MDB_pgsql  The DB implementation for PostGreSQL. Inherits MDB_Common.               When calling MDB::factory or MDB::connect for PostGreSQL               connections, the object returned is an instance of this               class.
MDB_Date     This class provides several method to convert from and to               MDB timestamps.
MDB_Manager  This class handles the xml schema management.

		Create a new MDB connection object and connect to the specified  database
IMPORTANT: In order for MDB to work properly it is necessary that  you make sure that you work with a reference of the original  object instead of a copy (this is a PHP4 quirk).
For example:      $mdb =& MDB::connect($dsn);           ^^  And not:      $mdb = MDB::connect($dsn);           ^^


    

  • Return: a newly created MDB connection object, or a MDB                   error object on error
    • 

  • See: MDB::parseDSN
