This function is as simple as it sounds, it returns the name of the database your are currently connected to on the handle retrieved from a pg_connect() call.



<?php

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



    if ($pgsql_conn) {

        print "Successfully connected to database: " . pg_dbname($pgsql_conn) .

         " on " .  pg_host($pgsql_conn) . "<br/>\n";

    } else {

        print pg_last_error($pgsql_conn);

        exit;

    }

?>

Successfully connected to database: mark on localhost<br/>



Again this function is much more useful when you are changing which database you are connected to in your program.
