Answer 1

我已经解决了这个问题。实际上它是base64编码。在使用 base64_decode 解码后，我能够生成 pdf。

Answer 2

header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="service.pdf"');
echo base64_decode($byte_string);

刚为我工作。

Answer 3

You could just echo it with headers.

header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="service.pdf"');
echo $byte_string;

header

But I cannot read provided string as PDF.
