    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;
    }
    ?>

    warning, at least on php-fpm 8.2.1 and nginx, getallheaders() will return "Content-Length" and "Content-Type" both containing emptystring, even for requests without any of these 2 headers. you can do something like

    <?php
    $request_headers     = getallheaders();
    if((    $request_headers["Content-Type"] ?? null) === "" && ($request_headers["Content-Length"] ?? null) === "") {
    // probably a getallheaders() bug, not actual request headers.
    unset($request_headers["Content-Type"], $request_headers["Content-Length"]);
    }
    ?>

    - might be a bug in nginx rather than php-fpm, i don't know. anyway a real request wouldn't leave them at emptystring
