ingres_connect

Open a connection to an Ingres II database (PHP 4 >= 4.0.2, PHP 5 <= 5.0.4)
resource ingres_connect ( [string database [, string username [, string password]]] )

Returns a Ingres II link resource on success, or FALSE on failure.

ingres_connect() opens a connection with the Ingres database designated by database, which follows the syntax [node_id::]dbname[/svr_class].

If some parameters are missing, ingres_connect() uses the values in php.ini for ingres.default_database, ingres.default_user, and ingres.default_password.

The connection is closed when the script ends or when ingres_close() is called on this link.

All the other ingres functions use the last opened link as a default, so you need to store the returned value only if you use more than one link at a time.
