pg_connect

(PHP 3, PHP 4, PHP 5)pg_connect -- Open a PostgreSQL connection

Описание

resource pg_connect (string connection_string [, int connect_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.

Список параметров

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.

Возвращаемые значения

PostgreSQL connection resource on success, FALSE on failure.
