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.
