This is a simple example of this function, which returns the name of which PostreSQL Database you are currently connected to.



<?php

    $pgsql_conn = pg_connect("dbname=mark host=localhost");



    if ($pgsql_conn) {

        print "Successfully connected to: " . pg_host($pgsql_conn) . "<br/>\n";

    } else {

        print pg_last_error($pgsql_conn);

        exit;

    }

?>



This function is extremely useful for sites which connect to multiple Postgresql services.
