pg_connect Open a PostgreSQL connection &reftitle.description; resourcepg_connect stringconnection_string intconnect_type pg_connect opens a connection to a PostgreSQL database specified by the connection_string. If a second call is made to pg_connect with the same connection_string as an existing connection, the existing connection will be returned unless you pass PGSQL_CONNECT_FORCE_NEW as connect_type. The old syntax with multiple parameters $conn = pg_connect("host", "port", "options", "tty", "dbname") has been deprecated. &reftitle.parameters; connection_string The connection_string can be empty to use all default parameters, or it can contain one or more parameter settings separated by whitespace. Each parameter setting is in the form keyword = value. Spaces around the equal sign are optional. To write an empty value or a value containing spaces, surround it with single quotes, e.g., keyword = 'a value'. Single quotes and backslashes within the value must be escaped with a backslash, i.e., \' and \\. The currently recognized parameter keywords are: host, hostaddr, port, dbname, user, password, connect_timeout, options, tty (ignored), sslmode, requiressl (deprecated in favor of sslmode), and service. Which of these arguments exist depends on your PostgreSQL version. connect_type If PGSQL_CONNECT_FORCE_NEW is passed, then a new connection is created, even if the connection_string is identical to an existing connection. &reftitle.returnvalues; PostgreSQL connection resource on success, &false; on failure. &reftitle.examples; ]]> &reftitle.seealso; pg_pconnect pg_close pg_host pg_port pg_tty pg_options pg_dbname
