README

本项目为Dompdf的默认中文支持版本.

官方默认不支持中文,要支持中文需要一堆的设置, 太过麻烦,所以直接适配了这个默认支持中文的版本.

加载后默认支持中文,不需要任何配置.

默认中文字体: hyqh 汉仪旗黑大小为 2.1M

使用示例

安装依赖

composer require tekintian/dompdf

默认使用中文字体

use Dompdf\Dompdf;

 //初始化Dompdf对象
$dompdf = new Dompdf();

//创建HTML内容 
$html = '<h1 style="font-size:5rem;color:blue;">你好Dompdf!</h1><h2>我默认使用的是中文字体</h2>';
$dompdf->loadHtml($html);

$dompdf->loadHtml($html);

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

//将html转为PDF
$dompdf->render();

//Output the generated PDF to Browser
$pdfname = '你好PDF.pdf';

//下载生成的pdf文件
//$dompdf->stream($pdfname);

//将生成的pdf保存到服务器
file_put_contents($pdfname, $dompdf->output());

//将生成的pdf文件渲染到页面
// $dompdf->stream($pdfname, [
//     'compress' => 0,
//     'Attachment' => 0
// ]);

自行添加其他中文字体

# 将 load_font.php 拷贝到项目根目录(和vendor同级目录)
cp vendor/tekintian/dompdf/load_font.php ./

# 安装字体到库中
php ./load_font.php "字体名称" "字体路径.ttf"

使用中文字体

在需要进行pdf转换的HTML中使用中文字体的方式与普通的HTML相同，可以是内联样式，也可以使用在style标签中。

<body style="font-family:hyqh">手动指定中文字体</body>

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 in Discussions.

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

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

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) . '" ...>';
```
Watch dompdf/dompdf#320 for progress
Does not support CSS flexbox.
Does not support CSS Grid.
