// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, &#39;&#39;, PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, &#39;&#39;, PDF_FONT_SIZE_DATA));
// set default monospaced font

    $pdf->setLanguageArray($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(&#39;dejavusans&#39;, &#39;&#39;, 14, &#39;&#39;, 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(&#39;enabled&#39;=>true, &#39;depth_w&#39;=>0.2, &#39;depth_h&#39;=>0.2, &#39;color&#39;=>array(196,196,196), &#39;opacity&#39;=>1, &#39;blend_mode&#39;=>&#39;Normal&#39;));
// Set some content to print
$html = <<<EOD
<h1>Welcome to <a href="http://www.tcpdf.org" style="text-decoration:none;background-color:#CC0000;color:black;"> <span style="color:black;">$kid_name</span><span style="color:white;">PDF</span> </a>!</h1>
<i>This is the first example of TCPDF library.</i>
<p>This text is printed using the <i>writeHTMLCell()</i> method but you can also use: <i>Multicell(), writeHTML(), Write(), Cell() and Text()</i>.</p>

EOD;
      // Print text using writeHTMLCell()
      $pdf->writeHTMLCell(0, 0, &#39;&#39;, &#39;&#39;, $html, 0, 1, 0, true, &#39;&#39;, true);
      // ---------------------------------------------------------
      // Close and output PDF document
      // This method has several options, check the source code documentation for more information.
      $pdf->Output(&#39;example_001.pdf&#39;, &#39;F&#39;);
      return  &#39;example_001.pdf&#39;;
    }
}

Note:

• Because TCPDF uses delimiters to output html and other content, $html in the above code must be in the same format until EOD.

• For the problem of garbled Chinese characters, just change the font to $pdf->SetFont('cid0cs', '', 8).

Front-end display

 <object :data="example_001.pdf" type="application/pdf" style="width:100%;height:1200px;"></object>
