mPDF is a PHP library which generates PDF files from UTF-8 encoded HTML.

It is based on FPDF and HTML2FPDF (see CREDITS), with a number of enhancements. mPDF was written by Ian Back and is released under the GNU GPL v2 licence.

Note: If you are viewing this file on mPDF Github repository homepage or on Packagist, please note that the default repository branch is development which can differ from the last stable release.

Requirements

mPDF 7 requires PHP ^5.6 || ~7.0.0 || ~7.1.0 || ~7.2.0. PHP mbstring and gd extensions have to be loaded.

Additional extensions may be required for some advanced features such as zlib for compression of output and embedded resources such as fonts, bcmath for generating barcodes or xml for character set conversion and SVG handling.

mPDF has some problems with fetching external HTTP resources with single threaded servers such as php -S. A proper server such as nginx (php-fpm) or Apache is recommended.

Installation

Official installation method is via composer and its packagist package mpdf/mpdf.

$ composer require mpdf/mpdf

Usage

The simplest usage (since version 7.0) of the library would be as follows:

<?php

require_once __DIR__ . '/vendor/autoload.php';

$mpdf = new \Mpdf\Mpdf();
$mpdf->WriteHTML('<h1>Hello world!</h1>');
$mpdf->Output();

This will output the PDF inline to the browser as application/pdf Content-type.

Setup & Configuration

All configuration directives can be set by the $config parameter of the constructor.

It is recommended to set one's own temporary directory via tempDir configuration variable. The directory must have write permissions (mode 775 is recommended) for users using mPDF (typically cli, webserver, fpm).

Warning: mPDF will clean up old temporary files in the temporary directory. Choose a path dedicated to mPDF only.

<?php

$mpdf = new \Mpdf\Mpdf(['tempDir' => __DIR__ . '/tmp']);

By default, the temporary directory will be inside vendor directory and will have correct permissions from post_install composer script.

For more information about custom temporary directory see the note on Folder for temporary files in the section on Installation & Setup in the manual.

If you have problems, please read the section on troubleshooting in the manual.

Unit Testing

Unit testing for mPDF is done using PHPUnit.

To get started, run composer install from the command line while in the mPDF root directory (you'll need composer installed first).

To execute tests, run vendor/bin/phpunit from the command line while in the mPDF root directory.

Any assistance writing unit tests for mPDF is greatly appreciated. If you'd like to help, please note that any PHP file located in the /tests/ directory will be autoloaded when unit testing.
