Question

我使用TCPDF库生成PDF而我的代码是

include("tcpdf/tcpdf.php");
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example 001');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.' 001', PDF_HEADER_STRING, array(0,64,255), array(0,64,128));
$pdf->setFooterData(array(0,64,0), array(0,64,128));
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
$pdf->setFontSubsetting(true);
$pdf->SetFont('dejavusans', '', 14, '', true);
$pdf->AddPage();
$pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));

$html = "Muhammad Shoaib";

$pdf->writeHTML($html, true, false, true, false, '');
$pdf->Output('example_001.pdf', 'I');

它工作正常但是当我添加HTML代码时，它会给我错误，我的HTML代码是

$html = '<table>';
        $html .= '<tr>';
            $html .= '<td>';
                $html .= 'Test';
            $html .= '/<td>';
        $html .= '</tr>';
    $html .= '</table>';

，错误是

TCPDF ERROR: Some data has already been output, can't send PDF file

我找到了几个链接，但没有理解这个问题。

一些数据已经输出TCPDF
