Introduction - Connect -- Connecting and disconnecting a database

Описание

To connect to a database you have to use the function connect(), which requires a valid DSN as the first parameter. This parameter can either be a string or an array. If using an array, the array used gets merged with the default information:

$dsn = array(
    'phptype'  => false,
    'dbsyntax' => false,
    'username' => false,
    'password' => false,
    'protocol' => false,
    'hostspec' => false,
    'port'     => false,
    'socket'   => false,
    'database' => false,
);
Any elements you set override the defaults and the remainder stay at their defaults.

The second parameter is the optional $options array that can contain runtime configuration settings for this package. See setOption() for more information on the available settings.

In case of success you get a new instance of the database class. It is strongly recommened to check this return value with isError().

To disconnect use the method disconnect() from your database class instance.
