How to get the http headers from current request in PHP

Question

Is it possible to get the http headers of the current request with PHP? I am not using Apache as the web-server, but using nginx.

I tried using getallheaders() but I am getting Call to undefined function getallheaders().

Hello,

Try this code:

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