fsockopen problem

[dzoddi]

Hello

I'm trying to post some variables to a php page

function httpPost($fields, $url = '/sms.php')
{
	$qs = array();
	foreach ($fields as $k => $v)
		$qs[] = $k.'='.urlencode($v);
	$qs = join('&', $qs);

	$errno = $errstr = '';

	if ($fp = @fsockopen('xxx.xxx.com', 80, $errno, $errstr, 30)) 
	{
		fputs($fp, "POST ".$url." HTTP/1.1\r\n");
		fputs($fp, "Host: xxx.xxx.com\r\n");
		fputs($fp, "User-Agent: MSIE\r\n");
		fputs($fp, "Content-Type: text/www-form-urlencoded\r\n");
		fputs($fp, "Content-Length: ".strlen($qs)."\r\n");
		fputs($fp, "Connection: close\r\n");
		fputs($fp, "\r\n".$qs);

		$content = '';
		while (!feof($fp))
			$content .= fgets($fp, 1024);

		fclose($fp);
		return preg_replace("/^.*?\r\n\r\n/s", '', $content);
	}

	return false;
}

the problem is that the page that receive the post doesn't receive the variables.

Can you help me?
