Sending output to browser

[eluser]steelaz[/eluser]
Based on certain conditions, I want to break in the middle of controller and send custom output to the browser. I found a way to do this using private function _display() in output class, but perhaps there is proper way of doing it?

This is what I use right now:

Code:

$this->output->set_header($json_header);
$this->output->set_output(json_encode($result));
$this->output->_display();
exit(0);
