How to export data as CSV files in symfony

If you want to export the data in the database as a CSV file in symfony, try the following:
The code is as follows:
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:
The code is as follows:
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')?>
