Call to undefined function Jasny\SSO\getallheaders()

[Davyd Holovii]

Hello! I'm trying to implement SSO in my projects, but it doesn't work because I'm using nginx and php-fpm therefore getallheaders function is not available. The problem in getBrokerSessionID method. Can you add a fix for it?

Hi! The getallheaders() isn't always available. You could use this code to make the function available if it's not present (got it from PHP.net):

{ 
    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; 
    } 
} 

The only value actually required is the Authorization header, so you could get it out of the $_SERVER global instead of using the original getallheaders() or the above function.

I see. I just think would be great to create new method like this:

protected function getAllHeaders()
{
    if (!function_exists('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; 
    } 
    return getallheaders();
} 

and use this method in getBrokerSessionID

If you add the function in general, you can just use Jasny's package without having to modify it.
