Dompdf: HTML to PDF Converter for PHP

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.

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 (see "Limitations" below)

Requirements

  • PHP version 7.1 or higher
  • DOM extension
  • MBString extension
  • php-font-lib
  • php-svg-lib

Note that some required dependencies may have further dependencies (notably php-svg-lib requires sabberworm/php-css-parser).

Recommendations

  • OPcache (OPcache, XCache, APC, etc.): improves performance
  • GD (for image processing)
  • 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.

Easy Installation

Install with composer

To install with Composer, simply require the latest version of this package.

composer require dompdf/dompdf

Make sure that the autoload file from Composer is loaded.

// somewhere early in your project's loading, require the Composer autoloader
// see: http://getcomposer.org/doc/00-intro.md
require 'vendor/autoload.php';

Download and install

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

Use the packaged release autoloader to load dompdf, libraries, and helper functions in your PHP:

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

Note: packaged releases are named according using semantic versioning (dompdf_MAJOR-MINOR-PATCH.zip). So the 1.0.0 release would be dompdf_1-0-0.zip. This is the only download that includes the autoloader for Dompdf and all its dependencies.

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/lib

git clone https://github.com/PhenX/php-font-lib.git php-font-lib
cd php-font-lib
git checkout 0.5.1
cd ..

git clone https://github.com/PhenX/php-svg-lib.git php-svg-lib
cd php-svg-lib
git checkout v0.3.2
cd ..

git clone https://github.com/sabberworm/PHP-CSS-Parser.git php-css-parser
cd php-css-parser
git checkout 8.1.0

Require dompdf and it's dependencies in your PHP. For details see the autoloader in the utils project.

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();
$options = $dompdf->getOptions();
$options->setDefaultFont('Courier');
$dompdf->setOptions($options);

See Dompdf\Options for a list of available options.

Resource Reference Requirements

In order to protect potentially sensitive information Dompdf imposes restrictions on files referenced from the local file system or the web.

Files accessed through web-based protocols have the following requirements:

  • The Dompdf option "isRemoteEnabled" must be set to "true"
  • PHP must either have the curl extension enabled or the allow_url_fopen setting set to true

Files accessed through the local file system have the following requirement:

  • The file must fall within the path(s) specified for the Dompdf "chroot" option

Limitations (Known Issues)

  • Table cells are not pageable, meaning a table row must fit on a single page.
  • Elements are rendered on the active page when they are parsed.
  • Embedding "raw" SVG's (<svg><path...></svg>) isn't working yet, you need to either link to an external SVG file, or use a DataURI like this:
$html = '<img src="data:image/svg+xml;base64,' . base64_encode($svg) . '" ...>';

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 ($options->setIsHtml5ParserEnabled(true);) or run your HTML through a HTML validator/cleaner (such as Tidy or the W3C Markup Validation Service).
  • Table cells are not pageable, meaning a table row must fit on a single page.

Introduction to Structured Query Language SQL pdf

SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.

Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:

1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.

2. Every database seller needs an approach to separate its item from others.

Right now, contrasts are noted where fitting.
