If you need send string as file to the client you can do it as follows:
public function sendIcs() { $icsString = $this->Calendars->generateIcs(); $response = $this->response; // Inject string content into response body $response = $response->withStringBody($icsString); $response = $response->withType('ics'); // Optionally force file download $response = $response->withDownload('filename_for_download.ics'); // Return response object to prevent controller from trying to render // a view. return $response; } In this example you can see how can you send string as iCal file.
