I don't think that FAQ solves that problem.
Look at the source code of Apache server. There
are several tests of the variable "force-response-1.0" 
there. The problem is not that php code variable
is $force-response-1_0, that's OK, but the real
problem is that apache variable name in r->subprocess_env
is changed too. That's side effect and not pleasent.

This is mentioned in http://uk.php.net/manual/en/faq.html.php#AEN63677
. Impossible to find if you don't know where to find it. So changing this to a documentation
problem.

(the issue is that invalid characters in incoming variable names, like dots, are converted to
underscores. This happens with any incoming variable name, be it GET, POST, ENV, or whatever.)

Changed subject

Apache module mod_setenvif sets variables in 
r->subprocess_env. If variable name contains character ".", then
mod_php4.c/sapi_apache_register_server_variables() will
replace it with "_". This breaks internal
variables like force-response-1.0 (php changes it to
force-response-1_0).

Solution: the key in the php_register_variable() call
should be a copy of the real key.
