XML response from asp page

I have been trying to send xml message from php to asp and output response to my php page using CURL but having no luck in receiving any response. This is what I have tried:

<?php

$post_string = "xmlmessage=<?xml version='1.0' encoding='UTF-8'?>
$url = "https://someweb.asp"; 
<abc>
<UserId>123</UserId> 
</abc>";

//$header  = "POST HTTPS/1.0 \r\n";
$header = "Content-type: text/xml \r\n";
$header .= "Content-length: ".strlen($post_string)." \r\n";
$header .= "Content-transfer-encoding: text \r\n";
$header .= "Connection: close \r\n\r\n"; 
$header .= $post_string;

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);

$output = curl_exec($ch);
$info = curl_getinfo($ch);

if ($output == false || $info['http_code'] != 200) {
  $output = "No cURL data returned for $url [". $info['http_code']. "]";
  if (curl_error($ch))
    $output .= "\n". curl_error($ch);
  }
else
    {curl_close($ch);}

echo $output;
?>

Can anyone please guide me where i am wrong?

try:

<?php
//do not put the $url within the XML (like in your original post)
$url = "https://someweb.asp"; 

$post_string =<<<XML
<?xml version='1.0' encoding='UTF-8'?>
<abc>
<UserId>123</UserId> 
</abc>
XML;

$post_string='xmlmessage='.rawurlencode($post_string);
echo $post_string;

/*
//$header  = "POST HTTPS/1.0 \r\n";
$header = "Content-type: text/xml \r\n";
$header .= "Content-length: ".strlen($post_string)." \r\n";
$header .= "Content-transfer-encoding: text \r\n";
$header .= "Connection: close \r\n\r\n"; 
$header .= $post_string;
*/

$ch = curl_init($url);


curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);

//get rid of the following and use the POST headers    
//curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);

//add the following two headers (for POST requests)
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$post_string);

$output = curl_exec($ch);
$info = curl_getinfo($ch);

if ($output == false || $info['http_code'] != 200) {
  $output = "No cURL data returned for $url [". $info['http_code']. "]";
  if (curl_error($ch))
    $output .= "\n". curl_error($ch);
  }
else
    {curl_close($ch);}

echo $output;
?>
