Method for setting $_SERVER var in httpd.conf or php.ini?

[grue]

Hi,

I have some scripts that were coded for a custom webserver that supports PHP.

This custom webserver defined a $SERVER['xyz'] variable for each request being processed. So, for every script run, you could access $SERVER['xyz'].

Is there any way I can do this for Apache by putting some "php_value" directive in httpd.conf, setting some configuration variable in php.ini, or something?

Note: I do not want to set a variable in php.ini and access it with get_cfg_var().

If I do that, I'd have to modify the scripts, which I don't want to do.

thanks for any help you can provide!
