在PHP7.3中将PDF文件的页面提取为新的PDF文件

我用过 Mpdf 对于一个同样的问题。通过执行以下操作,您可以轻松创建新的pdf文档并导入pdf的现有页面:

<?php

$sourceFilePath = '/tmp/my-pdf-with-4-pages.pdf';
$destinationFilePath = 'output/my-pdf-with-3-pages.pdf';
  
$mpdfConfig = [];
$mpdf = new Mpdf($mpdfConfig);

// $mpdf->SetImportUse(); only necesseray for mpdf >=4 && <8
$pageCount = $mpdf->setSourceFile($sourceFilePath); // number of pages in your source pdf file 

$pageNumbersToImport = [1,2,3];
$pageNumbersToImportCount = count($pageNumbersToImport);

// importing pages defined in $pageNumbersToImport
for ($pageNumber = 1; $pageNumber <= $pageCount; $pageNumber++) {
  if (!in_array($pageNumber, $pageNumbersToImport, true)) {
    continue;
  }
  
    $templateId = $mpdf->ImportPage($pageNumber); // get page content of page number as template of source pdf file
  $mpdf->UseTemplate($templateId); // add page number of source file to current mpdf generated file
  
  if ($pageNumber < $pageNumbersToImportCount) {
    $mpdf->AddPage(); // add empty page
  }
}

$mpdf->Output($destinationFilePath, 'F'); // write new pdf file, with pages 1-3 of source file
