html - PHP: Adobe Reader can't open PDF files created with mpdf -


i'm using mpdf create pdf files on fly, , files open fine in browser adobe gives me error:

adobe acrobat reader dc not open 'example-filename.pdf' because either not supported file type or because file has been damaged (for example, sent email attachment , wasn't correctly decoded).

i looked @ other questions (another mpdf + adobe error), , checked out pdf in text editor. found first part of file looked this:

<!doctype html> <head>     <title>         capstonedb     </title>     %pdf-1.4 %âãÏÓ

after removed %pdf-1.4 (including tab), file opened fine in adobe, great, except need able generated pdfs open in adobe without manually fiddling code every time.

here's wrapper function calls mpdf html , css:

include('../mpdf/mpdf.php');  function user_download_pdf($html, $css_file, $filename) {     $mpdf = new mpdf();     $stylesheet = file_get_contents($css_file);     $mpdf->writehtml($stylesheet,1);     $mpdf->writehtml($html,2);     $mpdf->output($filename, "d"); }

i never feed mpdf full html page, h3 , 1 or more tables. maybe need giving mpdf entire html page, including <head>, <body>, etc? there way change mpdf configuration or way call mpdf in php rid of html junk @ beginning of pdf file that's gunking up?

place

ob_clean();

immediately before

$mpdf->output();

without mpdf includes website page html , not html want in pdf, because headers have been sent elsewhere in code. can mess pdf adobe won't open it.
