Curl PHP PUT request changes file content -

i use put request curl php in 1 of scripts upload file external file repository using rest api. however, uploaded files contain information content-disposition, content-type , alpha-numeric code @ both beginning , end of file, rendering useless unless manually enditing again.

the unnecessary overhead looks this:

--------------------------e876c4b8eee91562 content-disposition: form-data; name="test_file"; filename="test_3.xlsx" content-type: application/octet-stream

the code use request is:

  $ch = curl_init($upload_url);   $cfile = new curlfile($file_realpath, 'application/octet-stream', $base_file_name);   $data = array ('test_file' => $cfile);   curl_setopt($ch, curlopt_customrequest, "put");   curl_setopt($ch, curlopt_postfields, $data);   curl_setopt($ch, curlopt_httpheader, array(     'accept:application/json',     'content-type:application/octet-stream',   ));   b2share_ignore_certificates($ch);   curl_setopt($ch, curlinfo_header_out, true);   curl_setopt($ch, curlopt_returntransfer, true);   $output = curl_exec($ch);    $http_status = curl_getinfo($ch, curlinfo_http_code);   $headersent = curl_getinfo($ch, curlinfo_header_out);    curl_close($ch); 

i can't change request post, rest api on other side needs put request. ideas on how rid of overhead?

ok. found answer question here: php curl post file without header

thus changing line

curl_setopt($ch, curlopt_postfields, $data); 

to

curl_setopt($ch, curlopt_postfields, file_get_contents($file_realpath)); 

fixes issue. not "clean" solution, works. i'd glad hear better solutions though.
