pg_connect Open a PostgreSQL connection resourcepg_connect stringconnection_string pg_connect returns a connection resource that is needed by other PostgreSQL functions. pg_connect opens a connection to a PostgreSQL database specified by the connection_string. It returns a connection resource on success. It returns &false; if the connection could not be made. connection_string should be a quoted string. ]]> The arguments available for connection_string includes host, port, tty, options, dbname, user, and password. If a second call is made to pg_connect with the same connection_string, no new connection will be established, but instead, the connection resource of the already opened connection will be returned. You can have multiple connections to the same database if you use different connection string. The old syntax with multiple parameters $conn = pg_connect ("host", "port", "options", "tty", "dbname") has been deprecated. See also pg_pconnect, pg_close, pg_host, pg_port, pg_tty, pg_options and pg_dbname.
