使用 TCPDF 添加外部 PDF 文件

Question

我正在使用TCPDF 生成 PDF 文档。现在我有一个场景，我想在我的TCPDF 生成文件之间添加外部 PDF 文件。我尝试了很多，但我失败了。

这是我的代码

<?php

require_once('tcpdf_include.php');
require_once('../tcpdf.php');
require_once('fpdi2/src/autoload.php');
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('PACRA');
$pdf->SetTitle('Client Undertaking');
$pdf->SetSubject('Client Undertaking');
$pdf->SetKeywords('Client Undertaking, PDF');
// set default header data
$pdf->setHeaderData('','', 'CLIENT ACCEPTANCE UNDERTAKING', '', array(0,64,255), array(0,64,128));
$pdf->setFooterData(array(0,64,0), array(0,64,128));
// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
// set margins
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
// set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
// set some language-dependent strings (optional)
if (@file_exists(dirname(__FILE__).'lang/eng.php')) {
    require_once(dirname(__FILE__).'lang/eng.php');
    $pdf->setLanguageArray($l);
}
// set default font subsetting mode
$pdf->setFontSubsetting(true);
// Set font
// dejavusans is a UTF-8 Unicode font, if you only need to
// print standard ASCII chars, you can use core fonts like
// helvetica or times to reduce file size.
$pdf->SetFont('dejavusans', '', 9, '', true);

// Add a page
// This method has several options, check the source code documentation for more information.
$pdf->AddPage();

// set text shadow effect
$pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));

//$utf8text = file_get_contents('../LICENSE.TXT', true);

// Set some content to print
$html = <<<EOD

只需使用正确的类，不要覆盖 $pdf 变量！

<?php

require_once('tcpdf_include.php');
require_once('../tcpdf.php');
require_once('fpdi2/src/autoload.php');

// create new PDF document
$pdf = new \setasign\Fpdi\TcpdfFpdi(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('PACRA');
//
// [...] the other code
//
// Print text using writeHTMLCell()
$pdf->writeHTMLCell(0, 0, '', '', $html, 0, 1, 0, true, '', true);

$pdf->AddPage();
$pdf->AddFont('courier');
$pdf->Write(10, 'page 1 created by TCPDF');
$pages = $pdf->setSourceFile('middle.pdf');
for($i=0; $i<$pages; $i++)
{
     $pdf->AddPage();
     $tplIdx = $pdf->importPage($i+1);
     $pdf->useTemplate($tplIdx, 10, 10, 200);
}
$pdf->AddPage();
$pdf->Write(10, 'page 2 created by TCPDF');

$pdf->Output($fileName, 'I');
