I'm playing with Mpdf for generating some html as a PDF but HTML tags don't seem to be working
I'm using Mpdf 7.1.6 and PHP 7.2
I can include stylesheets or not with no difference
$pdf = new \Mpdf\Mpdf(["format" => "A4"]);
$pdf->WriteHTML('<h1>Heading 1</h1>');
$pdf->WriteHTML('<h2>Heading 2</h2>');
$pdf->WriteHTML('<h3>Heading 3</h3>');
$pdf->WriteHTML('<h4>Heading 4</h4>');
$pdf->WriteHTML('<b>Bold</b>');
$pdf->WriteHTML('<center>Center</center>');
$pdf->WriteHTML('<table><tr><td>Table</td><td>Table</td></tr><tr><td>Table</td><td>Table</td></tr></table>');
$pdf->Output();
and I get the following
Not sure what the issue is.
Had to install Mpdf manually as I'm on a shared server and don't have command access nor access to composer so it could be a missing library of config file.
Any suggestions would be greatly appreciated as it's doing my head in.

Inside the laravel controller, When I do this
$html = '<h1><a name="top"></a>mPDF</h1>
<h2>Basic HTML Example</h2>
This file demonstrates most of the HTML elements.
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>';
$pdf = App::make('dompdf');
$pdf->loadHTML($html);
$pdf->save('my_stored_invoice.pdf')
It works perfectly.
But when i do this
$pdf = App::make('dompdf');
$pdf->loadView('pdf.invoice');
$pdf->save('my_stored_invoice.pdf');
My browser crashes with the calling URL, Also apache got slowed down.
I have set INI limit 2048 MB.
Please suggest me some way to get out of this problem.
Thanks in advance.
Isnt really an answer but too big to fit in comments... Few things to try:
Check installed:
PHP version 5.3.0 or higher
DOM extension
GD extension
MBString extension
php-font-lib
php-svg-lib
Writeable folders - check to make sure that you are able to write any temporary files.
Check your logs to see what crashed?
Check top / htop / activity monitor etc to see if you are using all your ram
Hello for this is fixed by changing the file permission
/vendor/thujohn/pdf
To allow domPDF to write temporally data
When I am trying to upload a pdf file and separating each page as pdf, with some pdf files it is working but some of pdf files show this error:
mPDF error: Unable to find xref table -" Maybe a Problem with auto_detect_line_endings"
My code:
ini_set('memory_limit', '512M');
$pagecount = Model::count_pages($documentPath.$journalDoc);
for ($i=1; $i<=$pagecount; $i++) {
$pdf = new mPDF('','Letter',12,'helvetica, sans-serif',200,0,0,20,0,10,'P');
$pdf->SetImportUse();
$pdf->SetSourceFile($documentPath.$journalDoc);
$import_page = $pdf->ImportPage($i);
$pdf->UseTemplate($import_page);
$pdf->Output($output_dir.$i.'.pdf', 'F');
}
This can be caused by PDF files of a version incompatible with the mPDF you're running. You can often circumvent the problem by regressing the source PDF files.
For instance, for mPDF v6.0 try brining your PDFs down to at most v1.4 using something like Ghostscript. (Where old.pdf is you're sourcefile)
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -o new.pdf old.pdf
Ghostscript won't write to the file it's reading so if you're doing this inline you'll have to dance;
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -o new.pdf old.pdf; mv -f new.pdf old.pdf
Increase the length size of this
public static $trailerSearchLength = 5500;
to this
public static $trailerSearchLength = 500000;
file location is: vendor\setasign\fpdi\src\PdfParser\CrossReference\CrossReference.php
This can be caused by the PDF file version that is incompatible with mPDF. You would better regress the PDF file version.
If you extracted a page from a file, you may have used an Adobe software.
Just use pdftk or pdfchain on Linux platform to solve the problem.
The version of FPDI in the offical repo of mPDF is very old. You may try to update to the latest version. Or you simply use the official version of FPDI which uses FPDF.
If you get a message about "unssported compression" you may check out the FPDI PDF-Parser add-on. Notice that there's a license incompatibility to mPDF.
I'd like to use DOMPDF, so I downloaded v0.6.2 on my PHP server (it meets the requests: php version, GD, mbstring...)
I'm a newbie so I didn't use git or composer, just downloaded the package and put it in a folder (named DOMPDF) of my webserver (Apache 2.4 / Windows 2008 server).
I wrote this very simple example and put it directly in the DOMPDF folder:
<?php
// c:\apache24\htdocs\dompdf\sample.php
print ("I see this in HTML output");
require_once("dompdf_config.inc.php");
print("Can't see this... and nothing that follows of course!");
$html = '<html><body><p>Hello world!</p></body></html>';
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");
?>
Nothing works!!! It seems I haven't the correct require directive. Is it an installation problem? What files must I include?
Thanks.
I had to manually install php-font-lib...
Everything OK now.
Below is the error that I am getting while I use the code
$output = shell_exec("/usr/bin/ebook-convert test.epub mech4eck.pdf");
<br>echo $output;
I need to run this with PHP only, and so I am trying to execute the shell commands. I am using Ubuntu 12.

I know none out here helped but I figured out on it my own.
Here is the trick
Rename the file /opt/lampp/lib/libgcc_s.so.1 to /opt/lampp/lib/libgcc_s.so.1.bak
Taddda it works :)
I am running the following code and giving me this error : FPDF error: This document (testcopy.pdf) probably uses a compression technique which is not supported by the free parser shipped with FPDI. I used another pdf named test.pdf and that works fine but it is giving me error in testcopy.pdf.
I think this is parser problem. Anyone know any other parser that can be used with fpdf to avoid this error?
My code:
require('fpdf17/fpdf.php');
require('fpdf17/fpdi.php');
// initiate FPDI
$pdf = new FPDI();
while (ob_get_level())
ob_end_clean();
header("Content-Encoding: None", true);
// set the sourcefile
$pagecount = $pdf->setSourceFile('testcopy.pdf');
I want to split pdf in two pdfs and want to attach both pdfs in file attachments field.How to save pdf to server. Can it be possible with fpdf?
Yes, Exactly the FPDF library supports only PDF version 1.4 & lesser. So to over come from this issue use GhostScript. This script helps to change the PDF versions dynamically.
(1) Download the Ghostscript here.
(2) Install the Ghostscript and define the environment variable PATH.
(3) Then, use the below php code to change the PDF version.
shell_exec( "gswin32 -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dNOPAUSE -dQUIET -dBATCH -sOutputFile=".$new_pdf." ".$old_pdf."");
(4) Now we get PDF with version 1.4 as output, then continue with FPDF.
Enjoy!
I had the same issue that PDFMerger does not work with certain PDF.
It seems that Adobe keep updating compression way of pdf extension.
I found solution with Chrome.
1. Open the PDF file(which does not work with PDFMerger) with Chrome
2. Right Click and Print
3. Change destination as [Save as PDF]
4. This exported PDF file is compatible with PDFMerger
The file needs to be PDF 1.4 (Acrobat 5) or lower. If you have Adobe Acrobat Pro you can change this with Document->Decrease File Size.
Looking through the answers so far, I wasn't able to resolve the issue.
Here's why and you may have the same issue so this answer would be invaluable to you too.
I did not have access to acrobat, so I couldn't downgrade the version of the original PDF. I wasn't in a position to purchase the newer version of the library which has upgraded encryption.
In the end I used an online PDF converter to downgrade my PDF file to version 5 (1.4)
If you are not able to find one, here's a link for completeness.

(bear in mind that the contents of a link may change)
Here is my answer from another topic:
"It can be overcome by re-saving the template and change compression type.
In Adobe Acrobat Pro go to File->Save As->Optimised PDF-> Popup left list - Clean Up,
Object Compression Options -> Change to "Compress document structure" -> OK to save"
Ref. Editing password protected pdfs with fpdi
GPL Ghostscript 8.70 (2009-07-31) / Centos 7
ghostscript -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dNOPAUSE -dQUIET -dBATCH -sOutputFile=new_file.pdf file.pdf
For those that don't have any of the pro versions of Acrobat:
I was having this problem with new versions of Word when trying to use the Office functionality to save to a PDF. It seems the PDF conversion tool supplied in Office is using the newer formats. Here's how I fixed it.
Install NitroPDF free version (May work with another free PDF creator that can be downloaded)
Go to the Word document and select 'Print'.
In the print options, instead of your printer, select 'Nitro PDF Creator (Reader 3)' or whatever the current version is.
A dialog box will open and allow you to select where to save the PDF.
The version saved was able to be opened by FPDF.
Hope it helps
In the case of Mac, you can open the PDF file in Preview and "export as PDF". The exported one can then be used.
I had a very similar error like you. My solution was to convert the pdf to a lower pdf version. Than everything worked like expected.
I hope that simple trick will help you!
