回答1:

I have resolved this issue. Actually it was base64 encodes. I was able to generate the pdf after decoding it using base64_decode.

回答2:

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

just worked for me.

回答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.
