sending post/get with php to TOR - php

Question

Is it possible to send post/get request to tor hidden service using php? Tor installed on my VPS and it opens 127.0.0.1:9050 scoks5 to access for tor network. I am trying to use POST via proxy like in example at the end, but nothing happens. Please tell me what is wrong in that way.
<?php
$proxy = "127.0.0.1";
$port = "9050";
$url = "https://mydomain.onion/input.php";
$fp = fsockopen($proxy, $port, $errno, $errstr, 30);
$url = #parse_url($url);
if($fp)
{
//reading data
if(($data = #file_get_contents('php://input')) === false)$data = '';
$request = "POST {$url['path']}." HTTP/1.1\r\n";
$request .= "Host: {$url['host']}\r\n";
if(!empty($_SERVER['HTTP_USER_AGENT']))$request .= "User-Agent: {$_SERVER['HTTP_USER_AGENT']}\r\n";
$request .= "Content-Type: application/x-www-form-urlencoded\r\n";
$request .= "Content-Length: ".strlen($data)."\r\n";
$request .= "Connection: Close\r\n";
//trying to send request
fwrite($fp, $headers.$data);
//trying to get answer
while(!feof($fp)) echo fread($fp, 1024);
fclose($fp);
}
else die;
?>

I used tor this way:
$proxy = "127.0.0.1";
$port = "9050";
$url = "https://mydomain.onion/input.php";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_PROXYTYPE, 7 );
curl_setopt ($ch, CURLOPT_PROXY, $proxy.':'.$port );
ob_start();
curl_exec ($ch);
curl_close ($ch);
$result = ob_get_contents();
ob_end_clean();
var_dump($result);
