如何在symfony中导出为CSV文件中的数据_PHP

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'); 

} 
 
在模板registrantsToCsvSuccess.php： 
 代码如下:

Title,Name,Email,Phone,Organisation,State,City,Country,Login Date,IpAddress 
 
getTitle() ?>,getName() ?>,getEmail() ?>,getPhone() ?>,getOrganisation() ?>,getState() ?>,getCity() ?>,getCountry() ?>,getLoginDate() ?>,getIpAddress() ?>, 
 
 
in the templates/csv.php: 
getRaw('sf_content') ?>
