PHP致命错误：第30行未找到类“ DOMPDF” [英] PHP Fatal error : Class 'DOMPDF' not found on line 30
问题描述
我正在使用DOMPDF从HTML生成PDF。
我已经从github复制了所有必需的文件（编码分支）。
I am using DOMPDF to generate PDFs from HTML. I have copied all required files from github (encoding branch). But it says class DOMPDF not error as below.
gitbub中dompdf_config.inc.php的链接： https://github.com/dompdf/dompdf/tree/encoding
link for dompdf_config.inc.php in gitbub : https://github.com/dompdf/dompdf/tree/encoding
此处是我的代码：
require_once("APIs/dompdf-encoding/dompdf_config.inc.php");
$cart_body='<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /><title>New Order Placed</title></head><body><p>Test Printing...</p></body></html>';
$dompdf = new DOMPDF();
$dompdf->load_html($cart_body);//body -> html content which needs to be converted as pdf..
$dompdf->render();
$dompdf->stream("sample.pdf"); //To popup pdf as download
实际输出为：
致命错误：在第30行的/home/web/www/test_dompdf.php
中找不到类'DOMPDF'
Fatal error: Class 'DOMPDF' not found in /home/web/www/test_dompdf.php on line 30
第30行是 $ dompdf = new DOMPDF（）;
注意：其他主分支工作正常。我需要这个编码分支，因为它可以解决与字体有关的编码问题。
Note: Other Master Branch is working fine. I need this encoding branch as it solves encoding font related issues.
推荐答案
我已经测试了您的代码，对我来说很好-sample.pdf文件正在浏览器中下载。我已经从 https://github.com/dompdf/dompdf/releases下载了库/tag/v0.6.1 网址（不仅是编码分支（
I've tested your code and it works fine for me - sample.pdf file is being downloaded in browser. I've downloaded library from https://github.com/dompdf/dompdf/releases/tag/v0.6.1 url (not only the encoding branch(
可能您没有将整个项目移至所选目录，或者您没有我下载了整个库，然后将整个下载目录内容移到了 APIs / dompdf-encoding 目录中，这里有文件 dompdf_config.inc.php 和目录 lib ， include 和 www 。
Probably you haven't moved the whole project to selected directory or you haven't downloaded the whole library. I moved the whole downloaded directory content to APIs/dompdf-encoding directory and I have here files dompdf_config.inc.php and directories lib, include and www.
编辑
编辑时，您只想使用编码分支，您需要做的是在文件开头添加以下代码：
As you edited you want to use only encoding branch, what you have to do is adding the following code at the beginning of your file:
use Dompdf\Adapter\CPDF;
use Dompdf\Dompdf;
use Dompdf\Exception;
EDIT2
整个工作代码：
<?php
use Dompdf\Adapter\CPDF;
use Dompdf\Dompdf;
use Dompdf\Exception;
require_once("APIs/dompdf-encoding/dompdf_config.inc.php");
$cart_body='<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /><title>New Order Placed</title></head><body><p>Test Printing...</p></body></html>';
$dompdf = new Dompdf();
$dompdf->load_html($cart_body);//body -> html content which needs to be converted as pdf..
$dompdf->render();
$dompdf->stream("sample.pdf"); //To popup pdf as download
我还更改了 DOMPDF 到 Dompdf 以防万一（在Windows中都可以使用）
I have also changed DOMPDF to Dompdf just in case (in Windows both are working)
