I am using Google Drive SDK to upload files by PHP. now I want to get the Link as string so that I can store it in my Database. But I don't have any idea on how to get it.. this is the code in creating the file in google drive using PHP.
$file = new Google_DriveFile();
$file->setTitle( 'new_pdf' );
$file->setMimeType( 'application/pdf' );
$createdFile = $service->files->insert( $file, array(
'data' => $stringContent,
));
