Добрый день всем.
Как собственно выдрать URL?
Код 200 отдает, редиректов не видно 301/302

<?php
$urlw = "http://alipromo.com/redirect/cpa/o/ri96mr07wjdcehsp3xifqjpkvueexxxj/"; 
$ch =  curl_init();
curl_setopt($ch, CURLOPT_URL, $urlw);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$page = curl_redir_exec($ch);
$page = curl_exec($ch);

curl_close($ch);

echo $page;
 
function curl_redir_exec($ch)
  {
  static $curl_loops = 0;
  static $curl_max_loops = 20;
  if ($curl_loops >= $curl_max_loops)
    {
    $curl_loops = 0;
    return false;
    }
	
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch , CURLOPT_RETURNTRANSFER , 1 ); 

  $data = curl_exec($ch);
  list($header, $data) = explode("\n\n", $data, 2);
  $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
 
  if ($http_code == 301 || $http_code == 302)
    {
    $matches = array();
    preg_match('/Location:(.*?)\n/', $header, $matches);
    $url = @parse_url(trim(array_pop($matches)));
    if (!$url)
      {
      $curl_loops = 0;
      return $data;
      }
    $last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL));
   
    if (!$url['scheme'])
      $url['scheme'] = $last_url['scheme'];
    if (!$url['host'])
      $url['host'] = $last_url['host'];
    if (!$url['path'])
      $url['path'] = $last_url['path'];
    $new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:'');
    echo $new_url.' --- '.$http_code.'<br>';
    curl_setopt($ch, CURLOPT_URL, $new_url);
    return curl_redir_exec($ch);
    }
  else
    {
    $curl_loops = 0;
    return $data;
    }
  }
?>

Куда копать?
