PDF不能使用php存储在文件夹中

我试图将我的pdf文件存储在数据库中的文件夹中。但它仅适用于MAMP服务器。我的代码如下：

$dompdf->load_html($html);
$dompdf->set_paper("A4", "landscape");
$dompdf->render();

 $dompdf->stream($projectdetail->project_name." - Cost Report.pdf", array("Attachment" => false));
 $canvas = $dompdf->get_canvas();
 $font = Font_Metrics::get_font("helvetica", "bold");
 $canvas->page_text(750, 570, "Page: {PAGE_NUM} of {PAGE_COUNT}", $font, 6, array(0,0,0));
 $canvas->page_text(25, 570, "II International P Ltd", $font, 6, array(0,0,0));
 $output = $dompdf->output();
 $file_to_save = '../files/'.$projectdetail->project_name.'/'.$projectdetail->project_name.'.pdf';
 file_put_contents($file_to_save, $output);

有人能帮我吗？

在代码的早期，您调用

$dompd->stream（）

。此方法流化PDF并停止脚本的执行。我不知道为什么它在MAMP上工作，但在其他服务器上不工作，但是如果你重新安排你的脚本，你应该会有更多的运气

$dompdf->load_html($html);
$dompdf->set_paper("A4", "landscape");
$dompdf->render();

$canvas = $dompdf->get_canvas();
$font = Font_Metrics::get_font("helvetica", "bold");
$canvas->page_text(750, 570, "Page: {PAGE_NUM} of {PAGE_COUNT}", $font, 6, array(0,0,0));
$canvas->page_text(25, 570, "II International P Ltd", $font, 6, array(0,0,0));
$output = $dompdf->output();

$file_to_save = '../files/'.$projectdetail->project_name.'/'.$projectdetail->project_name.'.pdf';
file_put_contents($file_to_save, $output);

$dompdf->stream($projectdetail->project_name." - Cost Report.pdf", array("Attachment" => false));

您是否尝试过这样->“文件/”。$projectdetail->project_name./'.$projectdetail->project_name..pdf'；s但不起作用您是否尝试过dirname（文件）
