我正在尝试使用以下代码使用 PHPexcel 和 MPDF 库创建 PDF 文档。但我收到错误消息 - “Adobe Reader 无法打开 '01simple-6.pdf' 因为它不是受支持的文件类型或因为文件已损坏（例如，它作为电子邮件附件发送并且未正确解码）。” 我究竟做错了什么？

<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');

if (PHP_SAPI == 'cli')
    die('This example should only be run from a Web Browser');

/** Include PHPExcel */
require_once '../Classes/PHPExcel.php';
$rendererName = PHPExcel_Settings::PDF_RENDERER_MPDF;
$rendererLibrary = 'mpdf.php';
$rendererLibraryPath = dirname(__FILE__).'/../../MPDF56/' . $rendererLibrary;

// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

// Set document properties
$objPHPExcel->getProperties()->setCreator("Maarten Balliauw")
                             ->setLastModifiedBy("Maarten Balliauw")
                             ->setTitle("PDF Test Document")
                             ->setSubject("PDF Test Document")
                             ->setDescription("Test document for PDF, generated using PHP classes.")
                             ->setKeywords("pdf php")
                             ->setCategory("Test result file");


// Add some data
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A1', 'Hello')
            ->setCellValue('B2', 'world!')
            ->setCellValue('C1', 'Hello')
            ->setCellValue('D2', 'world!');

// Miscellaneous glyphs, UTF-8
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A4', 'Miscellaneous glyphs')
            ->setCellValue('A5', 'éàèùâêîôûëïüÿäöüç');

// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('Simple');
$objPHPExcel->getActiveSheet()->setShowGridLines(false);

// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);


if (!PHPExcel_Settings::setPdfRenderer(
        $rendererName,

}

// Redirect output to a client’s web browser (PDF)

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'PDF');
$objWriter->save('php://output');
exit;

尝试关闭错误报告。我遇到了同样的错误，然后我看到了一些在文件输出之前输出的通知和警告。

所以我关闭了错误报告并开始工作。
