Problem submitting a POST request "by hand"

[Vallo Reima <vallo@xxxxxxxxx>]

Hello!

I send the parameters from one php script to another via POST method. 
The solution works (see example  below) but the receiver page loads ONLY 
if I include the echo $c; command after send_host (see PROBLEM!!! line). 
Otherwise a blank page loads without any error messages. The problem is 
same with Microsoft-IIS/5.1-PHP/5.0.3 and Apache/2.0.51-PHP/4.3.10... 
What can I do to get rid of this?
Thanks!
Vallo

function send_host($host,$path,$query,$others=''){
	$d="POST $path HTTP/1.1\r\nHost: $host\r\nContent-type: 
application/x-www-form-urlencoded\r\n${others}User-Agent: Mozilla 
4.0\r\nContent-length: ".strlen($query)."\r\nConnection: 
close\r\n\r\n$query";
	if (!$h = fsockopen($host,80)) {
		return -1;
	}
	else {
		stream_set_timeout($h,10);
	}
	if (fputs($h,$d) === FALSE) {
		return -2;
		}	
	else {
		$r = '';
	        while(!feof($h)) {
       	    $r .= fgets($h, 128);
		}
	}
	if (fclose($h) === FALSE) {
		return -3;
		}
	else {
		return $r;
	}
}

/* ... */

$c = send_host("$host_name","$redirect","$par");
if ($c < 0) {
   echo "<B>ERROR $c</B>";
} else {
   echo $c; /* PROBLEM!!! */
}
