header( 'Content-Disposition: attachment; filename='.$filename);



$phpWord = new \PhpOffice\PhpWord\PhpWord();

$section = $phpWord->addSection();



$section->addText('My test text');



$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007');

$objWriter->save( "php://output");
