This is not possible since they belong to 2 different processes.
The one that has the env variables set is a Java process (Jetty), the
one that runs PHP is php-fpm.

This is currently not possible out of the box.

It is common, however, to pass FastCGI variables along with the
request, and these can be retrieved in PHP via e.g.
$_SERVER['COUNTRY'] or getenv('COUNTRY') but *not* $_ENV['COUNTRY'].

What we can do is to allow to configure init-param names in
FastCGIProxyServlet, and then we can read those names and forward them
to PHP.
Please file an issue at

Something like:

<Call name="setInitParameter">
  <Arg>COUNTRY, DOMAIN, ...</Arg>

and we call System.getenv("COUNTRY"), etc.

What you can do right now is to override this:

class FarberFCGIServlet extends FastCGIProxyServlet {
  protected void customizeFastCGIHeaders(Request proxyRequest,
HttpFields fastCGIHeaders) {
    super.customizeFastCGIHeaders(proxyRequest, fastCGIHeaders);
    fastCGIHeaders.put("COUNTRY", System.getenv("COUNTRY"));
