我正在使用TCPDF在SmartJobBoard中工作。PDF已在旧服务器上正确生成。
将站点移至新服务器后，它在创建PDF发票时开始显示错误。TCPDF库显示以下错误。

为什么会发生此错误？
尝试插入...
//Change To Avoid the PDF Error
ob_end_clean();
如果这不起作用，请尝试使用ob_clean（）;。代替。
在您这样做之前：
$pdf->Output($filename, $output_dest);
发生此错误是因为TCPDF在最终渲染完成之前引发了错误。为了防止TCPDF创建无效的PDF，它决定崩溃。
以防万一TCPDF不再喜欢您，请查看DomPDF :)
TCPDF需要100％有效的XHTML语法
即使“ HTML Tidy”也不会向您显示所有html错误。就我而言，我的tr标签没有关闭，纠正后，警告消失了，但是pdf文件很丑。这个问题是通过改变，例如，解决了colspan=12通过colspan=”12”和rowspan=2通过rowspan=”2”。
