Dompdf

Dompdf is an HTML to PDF converter

At its heart, dompdf is (mostly) a CSS 2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer: it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes.

This document applies to the latest stable code which may not reflect the current release. For released code please navigate to the appropriate tag.

Check out the demo and ask any question on StackOverflow or on the Google Groups.

Features

Handles most CSS 2.1 and a few CSS3 properties, including @import, @media & @page rules
Supports most presentational HTML 4.0 attributes
Supports external stylesheets, either local or through http/ftp (via fopen-wrappers)
Supports complex tables, including row & column spans, separate & collapsed border models, individual cell styling
Image support (gif, png (8, 24 and 32 bit with alpha channel), bmp & jpeg)
No dependencies on external PDF libraries, thanks to the R&OS PDF class
Inline PHP support
Basic SVG support

Requirements

PHP version 5.3.0 or higher
DOM extension
GD extension
MBString extension
php-font-lib
php-svg-lib

Recommendations

OPcache (OPcache, XCache, APC, etc.): improves performance
IMagick or GMagick extension: improves image processing performance

About Fonts & Character Encoding

PDF documents internally support the following fonts: Helvetica, Times-Roman, Courier, Zapf-Dingbats, & Symbol. These fonts only support Windows ANSI encoding. In order for a PDF to display characters that are not available in Windows ANSI you must supply an external font. Dompdf will embed any referenced font in the PDF so long as it has been pre-loaded or is accessible to dompdf and reference in CSS @font-face rules. See the font overview for more information on how to use fonts.

The DejaVu TrueType fonts have been pre-installed to give dompdf decent Unicode character coverage by default. To use the DejaVu fonts reference the font in your stylesheet, e.g. body { font-family: DejaVu Sans; } (for DejaVu Sans). The following DejaVu 2.34 fonts are available: DejaVu Sans, DejaVu Serif, and DejaVu Sans Mono.

// see: http://getcomposer.org/doc/00-intro.md
require 'vendor/autoload.php';

Download and install

Download an archive of dompdf and extract it into the directory where dompdf will reside

You can download stable copies of dompdf from https://github.com/dompdf/dompdf/releases
Or download a nightly (the latest, unreleased code) from http://eclecticgeek.com/dompdf

Require dompdf, libraries, and helper functions in your PHP:

// include autoloader
require_once 'dompdf/autoload.inc.php';

Install with git

From the command line, switch to the directory where dompdf will reside and run the following commands:

git clone https://github.com/dompdf/dompdf.git
cd dompdf

git clone https://github.com/PhenX/php-font-lib.git lib/php-font-lib
cd lib/php-font-lib
git checkout 0.4
cd ..

git clone https://github.com/PhenX/php-svg-lib.git php-svg-lib
cd php-svg-lib
git checkout v0.1

Require dompdf, libraries, and helper functions in your PHP:

// include autoloader
require_once 'dompdf/autoload.inc.php';

Quick Start

Just pass your HTML in to dompdf and stream the output:

// reference the Dompdf namespace
use Dompdf\Dompdf;

// instantiate and use the dompdf class
$dompdf = new Dompdf();
$dompdf->loadHtml('hello world');

// (Optional) Setup the paper size and orientation
$dompdf->setPaper('A4', 'landscape');

// Render the HTML as PDF
$dompdf->render();

// Output the generated PDF to Browser
$dompdf->stream();

Setting Options

Set options during dompdf instantiation:

use Dompdf\Dompdf;
use Dompdf\Options;

$options = new Options();
$options->set('defaultFont', 'Courier');
$dompdf = new Dompdf($options);

or at run time

use Dompdf\Dompdf;

$dompdf = new Dompdf();
$dompdf->set_option('defaultFont', 'Courier');

See Dompdf\Options for a list of available options.

Limitations (Known Issues)

Dompdf is not particularly tolerant to poorly-formed HTML input. To avoid any unexpected rendering issues you should either enable the built-in HTML5 parser at runtime ($dompdf->set_option('isHtml5ParserEnabled', true);) or run your HTML through a HTML validator/cleaner (such as Tidy or the W3C Markup Validation Service).
Large files or large tables can take a while to render.
CSS float is in development and may not produce the desired result
