Make sure the directory have at least a 755. Also, use $_SERVER['DOCUMENT_ROOT']with your path to target the good directory :
确保目录至少有一个755. 此外，使用$_SERVER['DOCUMENT_ROOT']您的路径来定位好目录：
$nomFacture = $_SERVER['DOCUMENT_ROOT']."upload/factures/facture_".$idFacture.".pdf";
That will produce something like
那会产生类似的东西
/homez.742/coplayer/www/betatest/upload/factures/facture_12.pdf
/homez.742/coplayer/www/betatest/upload/factures/facture_12.pdf

Make sure you have not sending to output something else (like echo, var_dump, etc.) before generating PDF with Output("path_file", "F"). It is mandatory.
确保你没有发送到输出别的东西（如echo，var_dump，等与生成PDF之前）Output("path_file", "F")。这是强制性的。

make sure that file upload/factures/facture_98.pdfis not open anywhere when you run script. if it's open somewhere else then TCPDF can't open it.
确保运行脚本时文件upload/factures/facture_98.pdf未在任何地方打开。如果它在其他地方打开，则 TCPDF 无法打开它。
