A small Symfony 2 class for returning a response as a CSV file. Based on the Symfony JsonResponse class.
<?php
namespace Jb\AdminBundle\Http;
use Symfony\Component\HttpFoundation\Response;
class CsvResponse extends Response
{
protected $data;
protected $filename = 'export.csv';
public function __construct($data = array(), $status = 200, $headers = array())
{
parent::__construct('', $status, $headers);
$this->setData($data);
}
public function setData(array $data)
{
$output = fopen('php://temp', 'r+');
foreach ($data as $row) {
fputcsv($output, $row);
}
rewind($output);
$this->data = '';
while ($line = fgets($output)) {
$this->data .= $line;
}
$this->data .= fgets($output);
return $this->update();
}
public function getFilename()
{
return $this->filename;
}
public function setFilename($filename)
{
$this->filename = $filename;
return $this->update();
}
protected function update()
{
$this->headers->set('Content-Disposition', sprintf('attachment; filename="%s"', $this->filename));
if (!$this->headers->has('Content-Type')) {
$this->headers->set('Content-Type', 'text/csv');
}
return $this->setContent($this->data);
}
