Why is PHPWord giving a broken file?

Question

PHP

Good evening. I am using the following code to populate a file using PHPWord in yii2 on Ubuntu:

$PhpWord = new \PhpOffice\PhpWord\PhpWord();
                $document = $PhpWord->loadTemplate('/var/www/basic/web/Dogovor.docx'); //шаблон
                $document->setValue('company_name', $_POST['News']['title'] );
                $document->setValue('worker',  $_POST['News']['text']);
            header("Content-Type:application/vnd.ms-office");
            header('Cache-Control: max-age=0');
            header('Content-Disposition: attachment;filename="Dogovor.docx"');
            $document->saveAs('php://output');

When you try to open the file, it breaks down and offers to try to restore it, but this does not end with success.

If you save the completed file locally, and not give it to the browser, then there are no problems. What can be wrong?

Answer 1

The solution turned out to be to use the renderPartial() method instead of render().
