RE: [PHP] Finding what headers and content were already been sent
Ok, I have added apache_response_headers() which returns the current set of headers that Apache either knows about at this point (before the headers are sent) or the set of sent headers once they have actually gone out.

RE: [PHP] Finding what headers and content were already been sent
Ok, I understand about the request headers. While searching the archives, I've seen many requests from many people asking similar questions. You even answered some. The thing is that while there's a function to get request headers (getallheaders() or the $HTTP_ vars), there's no function to list the response headers, although you can easily see them in a phpinfo() page. How hard it'll be to do that function? Why no one adds it to PHP already? I mean, phpinfo() already knows of the response headers, why not just write a function so that scripts can have access to them. That of course is better than writing a private header() replacement, and saving headers there for a later access.

You can loop through $GLOBALS and check for vars that start with "HTTP_", but yes, you typically know which things you are interested in. And no, $HTTP_* are only the request headers.

RE: [PHP] Finding what headers and content were already been sent
And how do I KNOW which $HTTP_ variables are being set? Also, does $HTTP_ACCEPT_LANGUAGE mean that "Accept-Language" command has been sent by the browser? In my Windows configuration, using CGI version for example, I don't see also the headers sent by the server...
