dompdf codeigniter，我正在尝试渲染两个 html，但在渲染时出现错误

这里是我运行第二个渲染时发生的错误

    //  $this->pdf->load_html( 'reports/report_comb_1', $Ddata );
    $this->pdf->load_view( 'reports/report_comb_1', $Ddata );
    $this->pdf->render();
    $pdfoutput = $this->pdf->output();
    $filename = "$report_dir/"."cover3.pdf";
    $fp = fopen( $filename, "a" );
    fwrite( $fp, $pdfoutput );
    fclose( $fp );
    $this->pdf->load_view( 'reports/report_comb_2', $Ddata );
    $this->pdf->render();
    $pdfoutputu = $this->pdf->output();
    $filenameu = "$report_dir/"."imagleft3.pdf";
    $fp = fopen( $filenameu, "a" );
    fwrite( $fp, $pdfoutputu);
    fclose( $fp );

} else if( $reportCouvs[0] == 2 ) {
    $this->pdf->load_view('reports/report_comb_2', $Ddata ); 
}

在第二次渲染应用程序崩溃

是否可以使用 dompdf 渲染两个文件

我也遇到过这个问题。发生此错误的原因有几个。您可以检查三个选项：

  • 重新安装 DOMPDF 库
  • 确保 mbstring 已为 PHP 安装/配置/启用
  • 确保在循环时重新初始化或创建 DOMPDF 的新实例。

听起来您已经成功输出了一个 PDF，这表明前两个选项可能不是问题。我们看不到您与该问题相关的完整代码，但它似乎很可能是第三种选择。

如果是第三个，那么您将确保创建 pdf 的循环以以下行开头：

$this->pdf = new DOMPDF();
