get PHP custom response headers - php

Question

I´m sending an ajax request with a custom header called Authorization,
and I'm trying to get that header with PHP
if (!function_exists('getallheaders'))
{
function getallheaders()
{
$headers = array();
foreach ($_SERVER as $k => $v)
{
if (substr($k, 0, 5) == "HTTP_")
{
$k = str_replace('_', ' ', substr($k, 5));
$k = str_replace(' ', '-', ucwords(strtolower($k)));
$headers[$k] = $v;
}
}
return $headers;
}
}
$val = getallheaders();
echo $val;
and I get all the headers but not the custom one
val: Object{
Accept: "application/json, text/plain, */*"
Accept-Encoding: "gzip, deflate, sdch"
Accept-Language: "es-ES,es;q=0.8,en;q=0.6"
Connection: "keep-alive"
Host: "www.localhost.com"
Origin: "http://localhost"
Referer: "http://localhost/gestion/"
User-Agent: "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.101 Safari/537.36"
}
Any clues why I'm not getting header Authorization?

Answer 1

For custom headers the $_SERVER global in php documentation state that
There is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here. That said, a large number of these variables are accounted for in the » CGI/1.1 specification, so you should be able to expect those
so try to use apache_request_headers which may help you if your working with apache as a server
