Did you check it yourself? Do you think this is going to work?

Code:

function _get_chat_messages()

(int)last_chat_message_id = $this->session-> userdata ('last_chat_message_id_' . $chat_id);
{
  $chat_message = $this->chat_model->get_chat_message('$chat_id, $last_chat_message_id');

  if ($chat_messages->num_rows()> 0)
...

And I don't think this is going to work either

Code:

$this->this->session->set_userdata...
