二，编写php代码
controller/Index.php
<?php
namespace app\controller;
use app\BaseController;
use app\result\Result;
use Mpdf\Mpdf;
class Index extends BaseController
    //创建pdf文件
    public function makePdf() {
        $id=123;
        //用html形式生成pdf
        $html_content = '<p style="text-align: center;">
         <span style="color: rgb(153, 0, 0); font-size: 15px; text-align: center;">
             <img src="https://imgs-qn.iliangcang.com/ware/slider/1775.jpg" title="191335ODA5NzgyNzMwMzAy.jpg" alt="QQ截图20200306180410.jpg"/>
             </span>
    <p style="text-align: center;">
        <span style="color: rgb(153, 0, 0); font-size: 15px; text-align: center;">
        一年一度春节伴手礼大赛，带什么全家最开心?
        </span>

        <img src="http://img.baidu.com/hi/jx2/j_0040.gif"/>
    </p>';
        //tempDir指定临时文件目录，需要有可写入的权限，否则会报错
        $mpdf = new Mpdf(['mode'=>'utf-8',
            'format' => 'A4',
            'tempDir' => '/var/www/html/tmp'
        $mpdf->SetDisplayMode('fullpage');
        //自动分析录入内容字体
        $mpdf->autoScriptToLang = true;
        $mpdf->autoLangToFont = true;
        //文章pdf文件存储路径
        $fileUrl = "/var/www/html/pdf/article_".$id.".pdf";
        //以html为标准分析写入内容
        $mpdf->WriteHTML($html_content);
        //生成文件
        $mpdf->Output($fileUrl);
        //判断是否生成文件成功
        if (is_file($fileUrl)){
            return Result::Success("文件生成成功");
        } else {
            return Result::Error(1,"文件生成失败");
    //下载pdf文件
    public function downPdf() {
        $id=123;
        $fileUrl = "/var/www/html/pdf/article_".$id.".pdf";
        return download($fileUrl,"article_".$id.".pdf");
三，测试效果
1,生成pdf:
查看内容:
2,下载pdf
http://192.168.219.6:8000/index/downpdf
访问后文件会下载到本地
四，查看php和thinkphp的版本:
liuhongdi@lhdpc:/data/php/admapi$ php --version
PHP 8.1.1 (cli) (built: Dec 20 2021 16:12:16) (NTS)
thinkphp:
