Description:
------------
I'm trying to send some variables via POST with a socket connection to a HTML form.
The problem: 
The socket connection returns HTML-code from the form, but in the form I can't access the variables I sent (e.g. "go" is not set in $HTTP_POST_VARS and not in the global scope).

I took the sample code from the PHP manual, section "Stream functions", "Example 2. Making a POST request to an https server".

I think it should be no problem, that there are additional GET-parameters in the URI "d_content_kontakt.php" !?

Reproduce code:
---------------
$sock = fsockopen("linux", 80, $errno, $errstr, 30);
$data = 'go='.urlencode('sent');
fputs($sock, "POST /caranet_redesign/d_content_kontakt.php?art_angebot=Gebrauchtwagen&id_haendler=00000002&id_lang=00000001&typ=rm&hersteller=&schlafplaetze=&preis_von=&preis_bis=&id_fahrzeuge=00002158 HTTP/1.0\r\n");
fputs($sock, "Host: linux\r\n");
fputs($sock, "Content-type: application/x-www-url-encoded\r\n");
fputs($sock, "Content-length: " . strlen($data) . "\r\n");
fputs($sock, "Accept: */*\r\n");
fputs($sock, "\r\n");
fputs($sock, "$data\r\n");
fputs($sock, "\r\n");

$headers = "";
while ($str = trim(fgets($sock, 4096)))
  $headers .= "$str\n";

print "\n";

$body = "";
while (!feof($sock))
  $body .= fgets($sock, 4096);

fclose($sock);



Expected result:
----------------
variable "go" should contain "sent", but is not set in d_content_kontakt.php

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

And your PHP version is too old..

Sorry, Sniper, for stealing your time ;-)

But meanwhile I found the solution by myself:
I used the wrong content-type. Works much better with "application/x-www-form-urlencoded"...
