Save and download PDF
提问by user991830
I need to do 2 things together & at the same time with DOMPDF.
我需要用 DOMPDF 同时做两件事。
I need to do the following together - is this possible?
我需要一起做以下事情 - 这可能吗？
//print the pdf file to the screen for saving
$dompdf->stream("pdf_filename_".rand(10,1000).".pdf", array("Attachment" => false));
//save the pdf file on the server
file_put_contents('/home/stsnew/public_html/pdf/file.pdf', $dompdf->output());
The above works fine if $dompdf->streamand $dompdf->output()are done separately/individually , but when I try to run them together as shown above, it just crashes.
如果$dompdf->stream和$dompdf->output()分别/单独完成，则上述工作正常，但是当我尝试将它们一起运行时，如上所示，它只是崩溃。
Any help/advice would be really appreciated.
任何帮助/建议将不胜感激。

Why dont you swap them round create the pdf first as a file and then stream the created file back ?
为什么不交换它们，首先将 pdf 创建为文件，然后将创建的文件流回？
$file_to_save = '/home/stsnew/public_html/pdf/file.pdf';
//save the pdf file on the server
file_put_contents($file_to_save, $dompdf->output());
//print the pdf file to the screen for saving
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="file.pdf"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($file_to_save));
header('Accept-Ranges: bytes');
readfile($file_to_save);

回答晚了，但可能会有所帮助。
on set attachment true or 1
设置附件 true 或 1
$dompdf->stream("pdf_filename_".rand(10,1000).".pdf", array("Attachment" => true));
No need of file_put_contents() if you are just looking for download
如果您只是在寻找下载，则不需要 file_put_contents()
