int pg_connect (string conn_string)
Returns a connection index on success, or false if the connection could not be made. Opens a connection to a PostgreSQL database. The arguments should be within a quoted string.
Example 1. Using pg_connect arguments
<?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 ("user=lamb password=baaaa dbname=mary "); //connect to a database named "mary" with a username and password ?>
The arguments available include dbname port
, and password
This function returns a connection index that is needed by other PostgreSQL functions. You can have multiple connections open at once.
The previous syntax of: $conn = pg_connect ("host", "port", "options", "tty", "dbname") has been deprecated.
