MPDF: Import string from output method (STRING

There is an output method option to get a string that you can use as an attachment in an email, for example:

$mpdf->Output('', \Mpdf\Output\Destination::STRING_RETURN);

Is it possible to import this string again in a new MPDF-instance and add more content? I don't want to have to create individual PDF files first and then import them (importPage). My solution consists of independent PDF generators that should write to a shared PDF file.

CodePudding user response：

No, it is not possible.

The cleanest solution would be repeating the same PHP procedure with a new mPDF instance and then appending the new content.

<?php

$mpdf1 = new \Mpdf\Mpdf();
baseContent($mpdf1);
$mpdf1->Output('', \Mpdf\Output\Destination::STRING_RETURN);

$mpdf2 = new \Mpdf\Mpdf();
baseContent($mpdf2);
additionalContent($mpdf2);
$mpdf2->Output('', \Mpdf\Output\Destination::STRING_RETURN);
