RE: [PHP] How to suppress HTTP headers?
Just to catch up:
I'm trying to respond to a HTTP POST request without sending any HTTP
headers with the response (that is, reply with *content only*).
1) The CGI SAPI will always send some basic headers with any script output;
these include the status line ('HTTP/1.1 200 OK'), 'Content-type:', 'Date:'
and 'Content-length:'.
2) While the 'q' switch (php -q) is necessary and sufficient to suppress
HTTP header generation using the CLI ('command line interface'), it is not
clear to me how to apply this switch in a CGI configuration. Any ideas?
3) The header() command inserts or replaces headers to be sent by PHP.
However, header() (with no arguments) does not suppress header output, it
simply generates an error. Even if something like header('Content-type:')
suppressed the 'Content-type' header, how would we suppress all header
output including the status line ('HTTP/1.1 200 OK')?
4) Trying to use fsockopen() from the script receiving the POST request
fails because the client won't accept a redundant connection on the same
port/address it is currently using to issue the original POST request (it is
waiting for a response).
5) Mr. Lynch is right: this is NOT an HTTP compliant exchange. This is a bug
in the client machine that cannot be fixed (by me), but must be worked
around somehow.
6) All header information must be suppressed. That includes the status line,
too.
Tough little problem, eh guys?
I see three possible avenues to a solution.
1) Find some PHP command that will suppress header generation, or simply
circumvent it, if only as a side-effect.
2) Get Apache to not send headers for this page, maybe through SSI
directives, .htaccess file, or some other mechanism.
3) Write my own mini-server (to listen on port 6237 or something) to handle
these requests using socket calls in PERL, Java, or even the PHP CLI. I'm
not sure I could pull off programming something robust enough, frankly. I'd
rather hijack Apache to do the heavy lifting.
I'm not an expert in any of this, which is why I appreciate all the help I'm
getting. Thanks.

Re: [PHP] How to suppress HTTP headers?
Hi Thomas, I'm trying to respond to a HTTP POST request without sending any HTTP headers with the response (that is, reply with *content only*). This is really strange problem. :-) I don't know the answer, but I am pretty confident that you're not going to be able to eliminate headers through your PHP code. This is a question that an Apache expert might have a solution to, although I'd be surprised if you could force Apache to misbehave, which is exactly what you're wanting. I think your solution is going to wind up being to write your own web server that does not correctly adhere to the protocol, because I doubt you'll find existing software to do this. There is a web server written in PHP (odd, I know), that you can possibly hack to eliminate the HTTP header output. It's called Nanoweb: http://nanoweb.si.kz/ Hope that helps. Let us know how it goes. :-) Chris -- Chris Shiflett Brain Bulb, The PHP Consultancy http://brainbulb.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I believe that switch works on CGI, and that in CLI headers are
surpressed by default.

3) The header() command inserts or replaces headers to be sent by PHP.
However, header() (with no arguments) does not suppress header output, it
simply generates an error. Even if something like header('Content-type:')
suppressed the 'Content-type' header, how would we suppress all header
output including the status line ('HTTP/1.1 200 OK')?
The HTTP/1.1 200 OK is a header sent by your web server; PHP has NO
control over headers sent by the web server -- only those that PHP
appends to them.
5) Mr. Lynch is right: this is NOT an HTTP compliant exchange. This is a bug
in the client machine that cannot be fixed (by me), but must be worked
around somehow.
This is the real nut of the problem.
Tough little problem, eh guys?
I see three possible avenues to a solution.
1) Find some PHP command that will suppress header generation, or simply
circumvent it, if only as a side-effect.
Already noted, cano't be done.
2) Get Apache to not send headers for this page, maybe through SSI
directives, .htaccess file, or some other mechanism.
I don't think there's a way to do this -- HTTP headers are part of the
HTTP protocol, and that's what Apache tries to implement. But I can't
say with 100% certainty that someone hasn't done it. Search on the
apache web site.
3) Write my own mini-server (to listen on port 6237 or something) to handle
these requests using socket calls in PERL, Java, or even the PHP CLI. I'm
not sure I could pull off programming something robust enough, frankly. I'd
rather hijack Apache to do the heavy lifting.
I think this is likely to be the direction you'll need to go. This sort
of thing actually isn't too difficult to do -- I've used and tinkered on
PHP chat server implementations that do similar things. Perl has a
wealth of tools for creating net servers which, again, make this stuff
fairly trivial.
Good luck!
