// simple post method
// version 1.0 by Andrus (andrus@vnet.ee)

// Disclaimer:
// everyone can change or use this code however and wherever they want ;)

// NB! For posting to Microsoft platform webservers you may need to change newlines "\n" to "\r\n"
// Microsoft always breaks standards ...

// send out "browser" headers
function send_headers ($fp) {
fputs ($fp, "Accept: */*\n");
fputs ($fp, "Accept-Language: en\n");
fputs ($fp, "Connection: Keep-Alive\n");
fputs ($fp, "User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)\n");
}

// post data and return reply
function post_data ($host, $url, $data) {
$fp = @fsockopen ($host, 80, $errno, $errstr, 120);
$ret = "";
if (strncasecmp ($url, "http://", 7) == 0) $url = substr ($url, 7);
$p = strpos ($url, '/');
if (empty ($p)) {
$req = "/";
} else {
$req = substr ($url, $p);
}
if ($fp) {
fputs ($fp, "POST $req HTTP/1.0\n");
send_headers ($fp);
fputs ($fp, "Content-type: application/x-www-form-urlencoded\n");
$out = "";
while (list ($k, $v) = each ($data)) {
if(strlen($out) != 0) $out .= "&";
$out .= rawurlencode($k). "=" .rawurlencode($v);
}
$out = trim ($out);
fputs ($fp, "Content-length: ".strlen($out)."\n\n");
fputs ($fp, "$out");
fputs ($fp, "\n");
while(!feof($fp)){
$ret .= fgets($fp,128);
}
fclose ($fp);
}
return $ret;
}
// example how to use:

// following code will post variables "login" and "pass" to server "www.something.com" script "/submit.php"
$reply = post_data ("www.something.com", "/submit.php", array ("login" => $username, "pass" => $password));
