Ian, I think you misunderstood me.  I did not mean that nginx should
figure out the current value of PHP variable, but it should allow to
pass constructs like \${varname} into the environment, so that the
upstream FCGI manager, for example PHP-FPM, would then be able to
substitute variables accordingly.  Eg:

fastcgi_pass  PHP_VALUE  

I am not sure if PHP-FPM is able to do that at present, but, at least,
it allows such constructs in its own confirguration:

php_value[include_path] = "${include_path}:/my/other/include/path"

So I would assume the same could have been possible with PHP_VALUE
settings for FastCGI environment.
