The response object will always have a success key with the value true. If anything is passed to the function it will be encoded as the value for a data key.

Example arrays such as the following are converted to JSON:

$response = array( 'success' => true );                   //if $data is empty
$response = array( 'success' => true, 'data' => $data );  //if $data is set

		$response['data'] = $data;
