PEAR errors when try to acces a database

[fragorino88]

Ciao a tutti

Uso XAMPP su Ubuntu 10.10 e voglio imparare ad usare PEAR.

Per iniziare vorrei solo connetermi al mio DB

include ('db_login.php');
require_once ('DB.php');
$connection = DB::connect ("mysql://$db_username:$db_password@$db_host/$db_database");
if (DB::isError($connection)) {
die ("connection failed" .DB::errorMessage($connection));
}
$connection->disconnect();

ma quando viene interpretato lo script ecco cosa viene fuori:

qualche idea ?
