Query to json - HELP

[eluser]ojcarga[/eluser]
I don´t know if that is possible, but I´d do it this way,

Code:

$this->output
    ->set_content_type('application/json')
    ->set_output(json_encode(array('foo' => 'bar')));

array('foo' => 'bar') is the array containing the data retrieved from the database.
