ingres_connect

Open a connection to an Ingres database (PHP 4 >= 4.0.2, PHP 5 <= 5.0.5, PECL ingres:1.0-1.4.3)
resource ingres_connect ( [string database [, string username [, string password [, array options]]]] )

ingres_connect() opens a connection with the given Ingres database.

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.

Parameters

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

database

The database name. Must follows the syntax [node_id::]dbname[/svr_class].

username

The Ingres user name.

password

The password associated with username.
