示例1: array
/**
* Returns a MDB connection with the requested DSN.
* A newnew MDB connection object is only created if no object with the
* reuested DSN exists yet.
*
* 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:
* $mdb =& MDB::sngleton($dsn);
* ^^
* And not:
* $mdb = MDB::singleton($dsn);
* ^^
*
* @param mixed $dsn 'data source name', see the MDB::parseDSN
* method for a description of the dsn format.
* Can also be specified as an array of the
* format returned by MDB::parseDSN.
* @param mixed $options An associative array of option names and
* their values.
* @return mixed a newly created MDB connection object, or a MDB
* error object on error
* @access public
* @see MDB::parseDSN
