I am using a web service which returns me array of bytes and i am trying to convert it into pdf but finding some difficulties.

Returned bytes are more than thousand lines so i can not paste all but this is how it starts

/ViewerPreferences << 
/FitWindow true 
/PageLayout /SinglePage 
/NonFullScreenPageMode /UseNone 
>>

endobj 
5 0 obj 
<< 
/Length 1683 
/Filter [ /FlateDecode ] 
>> 
stream

I tried few solutions like

header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="service.pdf"');
echo hex2bin($byte_string);

or

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

Put your response in varriable, like in $data and if you are working in core php just write

file_put_contents('your_pdf_name.pdf',$data); 

and if you are doing in laravel

file_put_contents(public_path('your_folder_name/your_pdf_name.pdf'),$data);
