except a blank page. can any one please help me what
is going wrong with my script. 


$conn = pg_connect("user = $user dbname = $dbname host
= $host password = $pass");
if (!$conn)
        echo('could not establish connection with
database <br>');
$sql = "select * from experiment;"
$sth = pg_exec($connect,$sql)
if (! $sth){
die("Can't execute query".pg_errormessage());
