使用mpdf 生成pdf文件

首先安装mpdf composer require mpdf/mpdf

public function testpdf(Request $request){

        $mpdf = new Mpdf(['tempDir'=>runtime_path().'/pdftmp']);

        $mpdf->autoScriptToLang = true;  
        $mpdf->autoLangToFont = true; 

        $html = <<<EOD
        <h1 style='text-align:center;'>Hello World你好啊</h1>
EOD;

        $mpdf->WriteHTML($html);
        //public_path().'/pdf/'

        $file = public_path().'/pdf/'.time().'.pdf';
        $mpdf->Output($file,'F');

        return response()->download($file, time().'.pdf');
    }

生成结果
