$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {    die("Connection failed: " . $conn->connect_error);} 

$sql = 'SELECT * FROM clienti ORDER BY nome' ;$st = $conn->query($sql);//$st = mysql_query($sql) or die(mysql_error()); $output = '<select name="id">';while ($row = mysqli_fetch_assoc($st)) 

Ecco come era! Grazie mille!
