• apache_response_headers()获得全部 HTTP 响应头信息

it could be useful if you using nginx instead of apache 

There's a polyfill for this that can be downloaded or installed via composer:
https://github.com/ralouphie/getallheaders

Beware that RFC2616 (HTTP/1.1) defines header fields as case-insensitive entities. Therefore, array keys of getallheaders() should be converted first to lower- or uppercase and processed such.

dont forget to add the content_type and content_lenght if your are uploading file:

chears magno c. heck

Due to the else part.
}else{ 
          $out[$key]=$value; 
All server Variables are added to the headers list, and that's not the desired outcome.
