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.

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

    if (
$pgsql_conn) {
"Successfully connected to database: " . pg_dbname($pgsql_conn) .
" on " pg_host($pgsql_conn) . "<br/>\n";
    } else {

[mark@prodigy][*][~/public_html/php]>>>php pg_dbname.php
Content-type: text/html
X-Powered-By: PHP/4.3.1

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.
