This method initializes a new Auth_OpenID_Consumer instance to access the library.

• Auth_OpenID_OpenIDStore $store: This must be an object that implements the interface in Auth_OpenID_OpenIDStore. Several concrete implementations are provided, to cover most common use cases. For stores backed by MySQL, PostgreSQL, or SQLite, see the Auth_OpenID_SQLStore class and its sublcasses. For a filesystem-backed store, see the Auth_OpenID_FileStore module. As a last resort, if it isn't possible for the server to store state at all, an instance of Auth_OpenID_DumbStore can be used.
• bool $immediate: This is an optional boolean value. It controls whether the library uses immediate mode, as explained in the module description. The default value is False, which disables immediate mode.
• &$store
