Failure to connect to database using php. - Mailing list pgsql-novice

Hi,

I am using the following code to connect to my database.

<?

$db = pg_connect("dbname=friends");
echo pg_dbname();

?>

But there is nothing  displayed on the screen when I try it on my browser.

I use apache 4.3.9, redhat and postgresql 7.4.6. What am I doing wrong?
