connect [line 431]

mixed &connect(
mixed
$dsn, [array
$options = false])

Create a new MDB2 connection object and connect to the specified database

IMPORTANT: In order for MDB2 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: $db =& MDB2::connect($dsn); ^^ And not: $db = MDB2::connect($dsn); ^^

Return: a newly created MDB2 connection object, or a MDB2 error object on error
See: MDB2::parseDSN

mixed	`$dsn`	—	'data source name', see the MDB2::parseDSN method for a description of the dsn format. Can also be specified as an array of the format returned by MDB2::parseDSN.
array	`$options`	—	An associative array of option names and their values.
