it could be useful if you using nginx instead of apache

<?php
if (!function_exists('getallheaders'))
{
    function
getallheaders()
    {
          
$headers = [];
       foreach (
$_SERVER as $name => $value)
       {
           if (
substr($name, 0, 5) == 'HTTP_')
           {
              
$headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;
           }
       }
       return
$headers;
    }
}
?>

A simple approach to dealing with case insenstive headers (as per RFC2616) is via the built in array_change_key_case() function:

$headers = array_change_key_case(getallheaders(), CASE_LOWER);

There's a polyfill for this that can be downloaded or installed via composer:

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:

<?php
 
function emu_getallheaders() {
        foreach (
$_SERVER as $name => $value)
       {
           if (
substr($name, 0, 5) == 'HTTP_')
           {
              
$name = str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))));
              
$headers[$name] = $value;
           } else if (
$name == "CONTENT_TYPE") {
              
$headers["Content-Type"] = $value;
           } else if (
$name == "CONTENT_LENGTH") {
              
$headers["Content-Length"] = $value;
           }
       }
       return
$headers;
    }
?>

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.
