need Sockets and HTTP help

[darkreaper]

i am trying to write a script that can handle http requests and output them ... so far its kinda working ... but i am having problems with the post method! here is the code i hope someone can help me understand where i am mistaken:

<?php
function fsget($_url, $_port, $_timeout, $_do){
        $out="";
        $fp = fsockopen($_url, $_port, $_errno, $_errstr, $_timeout);
        if (!$fp){
                echo "$errstr ($errno) <br>\n";
        } else {
                fwrite($fp, $_do);
                while (!feof($fp)){
                        $out .= fgets($fp);
                }
                fclose($fp);
        }
        return $out;
}

$in="";
$in = "GET / HTTP/1.1\r\n";
$in .= "Accept: */*\r\n";
$in .= "Accept-Language: bg\r\n";
$in .= "Accept-Encoding: gzip, deflate\r\n";
$in .= "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; brip1; .NET CLR 1.1.4322)\r\n";
$in .= "Connection: Keep-Alive\r\n";
$in .= "Content-Length: " . strlen($in) . "\r\n\r\n";
$out = '';
echo fsget( <somehost> , 80, 30, $in);

$in="";
$in = "POST /login.php HTTP/1.1\r\n";
$in .= "Accept: */*\r\n";
$in .= "Accept-Language: bg\r\n";
$in .= "Content-Type: application/x-www-form-urlencoded\r\n";
$in .= "Accept-Encoding: gzip, deflate\r\n";
$in .= "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; brip1; .NET CLR 1.1.4322)\r\n";
$in .= "Connection: Keep-Alive\r\n";
$in .= "Cache-Control: no-cache\r\n\r\n";
$in .= "username=test&password=test&Submit=%C2%EB%E5%E7\r\n";
$in .= "Content-Length: " . strlen($in) . "\r\n\r\n";
$out = '';
echo fsget( <somehost> , 80, 30, $in);
?>
 

this code gets the main page of a host and outputs it
and then it posts some info on the login.php page...
only the first part of the code works ... the second one doesnt work i only get a header reply from the server nothing else...
HELP!

The content length listed in the header should be the length of the data you're posting, not the length of the whole header, e.g, if $datastream is an associative array

	foreach($datastream as $key=>$val)
	{ 
		if (!empty($reqbody)) $reqbody.= '&'; 

	$reqbody.= $key."=".urlencode($val); 
} 

$contentlength = strlen($reqbody); 

$reqheader ="POST $uri HTTP/1.1\r\n". 
			"Host: $host\n".
			"User-Agent: PostIt\r\n".
			"Connection: close\r\n".
			"Content-Type: application/x-www-form-urlencoded\r\n". 
			"Content-Length: $contentlength\r\n\r\n". 	// DOUBLE return here
			"$reqbody\r\n";

That double return after cache control is also probably causing trouble
