MySqli limit not binding to prepared statement -

i have made following prepared query. works if insert numbers manually ? are.

however, if bind parameters query not appear run. how can make can bind limit numbers?

    if ($statement = $db -> prepare("select blog_id, account_id, title, creation_time, body, timestamp      blogs      order creation_time desc      limit ?,?"))     {         $statement -> bind_param("ii", 2, 4);         $statement -> execute();         $statement -> store_result();     } 

when using bind_param(), not give values directly, variables hold them. need is:

$offset = 2; $limit = 4; $statement->bind_param('ii', $offset, $limit);
