PHP Fatal error : Class 'DOMPDF' not found on line 30
提问by logan
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.
我正在使用 DOMPDF 从 HTML 生成 PDF。我已经从 github（编码分支）复制了所有需要的文件。但它说 DOMPDF 类不是错误，如下所示。
link for dompdf_config.inc.php in gitbub : https://github.com/dompdf/dompdf/tree/encoding
gitbub 中 dompdf_config.inc.php 的链接：https: //github.com/dompdf/dompdf/tree/encoding
Here is my code :
这是我的代码：
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
Actual Output is :
实际输出是：
Fatal error: Class 'DOMPDF' not found in /home/web/www/test_dompdf.php on line 30
致命错误：在第 30 行的 /home/web/www/test_dompdf.php 中找不到“DOMPDF”类
Line 30 is $dompdf = new DOMPDF();
第 30 行是 $dompdf = new DOMPDF();
Note:Other Master Branch is working fine. I need this encoding branch as it solves encoding font related issues.
注意：其他主分支工作正常。我需要这个编码分支，因为它解决了编码字体相关的问题。

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/v0.6.1url (not only the encoding branch(
我已经测试了你的代码，它对我来说很好用 - sample.pdf 文件正在浏览器中下载。我已经从https://github.com/dompdf/dompdf/releases/tag/v0.6.1url下载了库（不仅是编码分支（
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-encodingdirectory and I have here files dompdf_config.inc.phpand directories lib, includeand www.
可能您没有将整个项目移动到选定的目录，或者您还没有下载整个库。我将整个下载的目录内容移动到APIs/dompdf-encoding目录，我在这里有文件dompdf_config.inc.php和目录lib，include以及www.
EDIT
编辑
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:
当您编辑时，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：
use Dompdf\Adapter\CPDF;
use Dompdf\Dompdf;
use Dompdf\Exception;

The whole working code:
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
I have also changed DOMPDFto Dompdfjust in case (in Windows both are working)
我也改变了DOMPDF以Dompdf以防万一（在Windows都是工作）
