推荐答案

您在使用使用:)

use关键字必须在文件的最外层范围内声明( 全局范围)或内部名称空间声明.这是因为 导入是在编译时而不是在运行时完成的，因此不能 块作用域.

The use keyword must be declared in the outermost scope of a file (the global scope) or inside namespace declarations. This is because the importing is done at compile time and not runtime, so it cannot be block scoped.

尝试以下代码:

use Dompdf\Dompdf; ob_start(); require_once '\dompdf\autoload.inc.php'; // instantiate and use the dompdf class $dompdf = new DOMPDF(); $html = " print_r($_POST); "; $dompdf->loadHtml($html); $dompdf->setPaper('A4', 'landscape'); $dompdf->render(); $pdf = $dompdf->output(); file_put_contents("page.pdf", $pdf); ?> <a href="./page.pdf" download="page.pdf">Download the pdf</a> <?php exit; ?>
