/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

$query = "SELECT zip, name FROM hotel.city ORDER by name";

if ($stmt = $maxdb->prepare($query)) {

   /* execute statement */
   $stmt->execute();

   /* bind result variables */
   $stmt->bind_result($name, $code);

   /* fetch values */
   while ($stmt->fetch()) {
       printf ("%s (%s)\n", $name, $code);
   }

   /* close statement */
   $stmt->close();
}

/* close connection */
$maxdb->close();
?>

Example #2 Procedural style

$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

$query = "SELECT zip, name FROM hotel.city ORDER by name";

if ($stmt = maxdb_prepare($link, $query)) {

   /* execute statement */
   maxdb_stmt_execute($stmt);

   /* bind result variables */
   maxdb_stmt_bind_result($stmt, $name, $code);

   /* fetch values */
   while (maxdb_stmt_fetch($stmt)) {
       printf ("%s (%s)\n", $name, $code);
   }

   /* close statement */
   maxdb_stmt_close($stmt);
}

?>
