Export to pdf problem

Hello, Can you please suggest me as to how to export mysql data to pdf. I have a form where it asks the user to either export the data to excel or to pdf. Excel is working fine but having problems when exporting to pdf. The simple code like below do not work. // We'll be outputting a PDF header('Content-type: application/pdf'); // It will be called downloaded.pdf header('Content-Disposition: attachment; filename="downloaded.pdf"'); Also tried using TCPDF but it takes a lot of time to export mysql data because i have millions of records. Kindly resolve the issue. -- Thanks and Regards, Mukta C. Jr. Developer(Development Division) Enjay Network Solutions Office Phone : 0260-3251732,3241732,3207531,3207532
