How to export data as a CSV file in Symfony

If you need to export database data as a CSV file in Symfony, try this;

In the action:

public function executeRegistrantsToCsv(){

      $id = $this->getRequestParameter('id');

    $c = new Criteria();
    $c->add(RegistrantPeer::EVENT_ID, $id);
    $c->add(RegistrantPeer::STATUS, 1);
    $this->aObjReg = RegistrantPeer::doSelect($c);

    $this->forward404Unless($this->aObjReg);
    $this->setlayout('csv');

    $this->getResponse()->clearHttpHeaders();
    $this->getResponse()->setHttpHeader('Content-Type', 'application/vnd.ms-excel');
    $this->getResponse()->setHttpHeader('Content-Disposition', 'attachment; filename=registrants_report_event_' . $id . '.csv');

  }

in the template registrantsToCsvSuccess.php:

Title,Name,Email,Phone,Organisation,State,City,Country,Login Date,IpAddress
<? foreach($aObjReg as $r): ?>
 <?= $r->getTitle() ?>,<?= $r->getName() ?>,<?= $r->getEmail() ?>,<?= $r->getPhone() ?>,<?= $r->getOrganisation() ?>,<?= $r->getState() ?>,<?= $r->getCity() ?>,<?= $r->getCountry() ?>,<?= $r->getLoginDate() ?>,<?= $r->getIpAddress() ?>,
<? endforeach ?>

in the templates/csv.php:

<?php echo $sf_data->getRaw('sf_content') ?>
