PHP provides a variety of libraries for processing Word documents, the most commonly used of which is the PHPWord library. By using PHPWord, we can easily read the content of Word documents and convert them into HTML format for further processing.

<?php
require_once &#39;PHPWord/Classes/PHPWord.php&#39;;
$PHPWord = new \PhpOffice\PhpWord\PhpWord();
$document = $PHPWord->loadTemplate(&#39;example.docx&#39;);
$html = $document->saveHTML();
echo $html;
?>

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, &#39;UTF-8&#39;, false);
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor(&#39;Author Name&#39;);
$pdf->SetTitle(&#39;TCPDF Example 001&#39;);
$pdf->SetSubject(&#39;TCPDF Tutorial&#39;);
$pdf->SetKeywords(&#39;TCPDF, PDF, example, test, guide&#39;);
$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);
$pdf->AddPage();
$pdf->writeHTML($html, true, false, true, false, &#39;&#39;);
$pdf->Output(&#39;example.pdf&#39;, &#39;I&#39;);
?>
