Zend Framework 2 - Rendering CSV data

Question

i have a model that returns car data with id, name, price etc. So i have a car controller and a csv action that fetches this data from a model:

$carTable = $         


        

Answer 1

This is based off the answer provided by Rob.

In Rob's answer, by assigning $response->getHeaders() to a new $headers variable, then applying the ->addHeaderLine to that new variable, it does not properly set the headers on the $response. So when returned, the headers were not attached to the response.

To fix this, simply add the headers directly to the $response shown below:

public function downloadAction()
{
    // magically create $content as a string containing CSV data

    $response = $this->getResponse();
    $response->getHeaders()
             ->addHeaderLine('Content-Type', 'text/csv')
             ->addHeaderLine('Content-Disposition', "attachment; filename=\"my_filen.csv\"")
             ->addHeaderLine('Accept-Ranges', 'bytes')
             ->addHeaderLine('Content-Length', strlen($content));

    $response->setContent($content);
    return $response;
}
