Question

我当前正在为data.php使用此代码，但出现此错误

Fatal error: Class 'setasign\Fpdi\FpdfTpl' not found

它说问题出在第24行的C：\ xampp \ htdocs \ pdf \ fpdi2 \ src \ Fpdi.php`。

我一直在该特定行中添加the setasign\Fpdi\FpdfTpl，并尝试重新加载它，但是没有响应，并且导致相同的错误

如果有人可以帮助我，那对我来说将是一个救生员。

只需要autoload.php，而无需手动安装类：

require_once('fpdf\fpdf.php');
require_once('fpdi2\src\autoload.php');

致命错误：在C：\ xampp \ htdocs \ pdf \ fpdi2 \ src \ Fpdi.php
