pg_connect
(PHP 3, PHP 4 )
pg_connect -- Open a PostgreSQL connection
Description
resource pg_connect ( string connection_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. Example 1. Using pg_connect()
<?php
$dbconn = pg_connect("dbname=mary");
//connect to a database named "mary"
$dbconn2 = pg_connect("host=localhost port=5432 dbname=mary");
// connect to a database named "mary" on "localhost"
at port "5432"
$dbconn3 = pg_connect("host=sheep port=5432 dbname=mary
user=lamb password=foo");
//connect to a database named "mary" on the host
"sheep" with a username and password
$conn_string = "host=sheep port=5432 dbname=test user=lamb
password=bar";
$dbconn4 = pg_connect($conn_string);
//connect to a database named "test" on the host
"sheep" with a username and password
?>
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 strings.
The old syntax with multiple parameters $conn = pg_connect("host",
"port", "options", "tty",
"dbname") has been deprecated.

pg_tty(), pg_options() and pg_dbname().
