nginx not sending DOCUMENT_ROOT to PHP?

I am using:

                location ~ \.php$ {
                        fastcgi_pass unix:/home/nginx/phpcgi/vidiscri;
                        fastcgi_index index.php;
                        fastcgi_param SCRIPT_FILENAME
                        fastcgi_param DOCUMENT_ROOT $document_root;
                        include conf/fastcgi_params;

To send PHP over to be parsed by php-fpm , but the problem is,
DOCUMENT_ROOT variable isn't being sent to PHP it keeps saying:

_SERVER["DOCUMENT_ROOT"]	/usr/local/nginx/html

Any specific reason why its doing this?

You can check for yourself here:

conf/fastcgi_params has:

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;
