Why is $mysqli->info empty?

Question

MySQL

fiddling with prepared queries, need to see the last executed query...
what am i doing wrong?

// выплняем запросы
$db->query("DROP TABLE test");
$db->query("CREATE TABLE test(id INT, text VARCHAR(50))");

echo "Последний запрос: ".$db->info."<br>";

here is the contents of the array(object properties):
[connect_errno] => 0 [connect_error] => [errno] => 0 [error] => [field_count] => 0 [host_info] => localhost via TCP/IP [info] = > [insert_id] => 0 [server_info] => 5.5.25 [server_version] => 50525
requests are running, everything is ok, but the last one is not showing...
