Nginx: modifying http_host header using the value from x_custom_header

I've been trying to do this thing for while but nothing working out for me. Hoping if anyone here can help....

The php app here reads $_SERVER['HTTP_HOST'] and then judging host part of the header, it decides which site to serves. The issue here, Nginx receives the headers as $http_host = mainweb.prd.mydomain.net and $x_custom_header = bob (or alice, joe etc.). I need to [re]set the value for http_host to bob.prd.mydomain.net. I suppose I need to do something like this:

set $host_header "${x_custom_header}.prd.mydomain.net";
proxy_set_header Host $host_header;

But this is obviously not working. Any idea how can I do that. All of the example that I can see here is actually for URL redirection, which is actually changing the URL in the browser, which I absolutely don't want. Any idea how can I do that? Any pointer to the right direction will be very much appreciate.
