 if(function_exists("curl_init")){
  $ch = curl_init($url);
  curl_setopt($ch, CURLOPT_HEADER, true);
  curl_setopt($ch, CURLOPT_NOBODY, true);

  $response = curl_exec($ch);
  curl_close($ch);
 }
 else{
  $url_parts = parse_url($url);
  $sock = fsockopen($url_parts['host'], (isset($url_parts['port']) ? (int)$url_parts['port'] : 80));
  $request = "HEAD " . $url_parts['path'] . (isset($url_parts['query']) ? '?'.$url_parts['query'] : '') . " HTTP/1.1\r\n";
  $request .= 'Host: ' . $url_parts['host'] . "\r\n";
  $request .= "Connection: Close\r\n\r\n";
  fwrite($sock, $request);
  $response = fread($sock, 2048);
  fclose($sock);
 }

 $header = "Location: ";
 $pos = strpos($response, $header);
 if($pos === false){
  return false;
 }
 else{
  $pos += strlen($header);
  $redirect_url = substr($response, $pos, strpos($response, "\r\n", $pos)-$pos);
  return $redirect_url;

$url = 'http://www.google.com/aclk?sa=L&ai=CrCejFqkOVOKWOI-kugTN6oLYAvnJlJQFmZ-zhcEBsICmBhABKAVQtvqyowVgM8gBAakC66asdGZRgT6qBCZP0CBGn079-YW7-A7S8GWCAhS00aM1g5em2pp3jm0DQzu_bEXDIYAH19CNEogHAZAHAqgHpr4b&num=4&sig=AOD64_22epSqlycp5HsAdE2QbJccaNwJzw&rct=j&q=&ved=0CKIBENEM&adurl=http://example.net/accounting-software.html';

I think you need to explain your problem rather than just posting the code.

What does not work? What is the result you are getting and what do you expect to get?

[phranque]

i would add some error checking/reporting to your code.

More explanation of my query -
* Paste this URL to browser - [google.com...]
* You will see results with ads.
* Need to develop such solution which will return those URL of search results.

Special case - Click on any ads. They will be redirected to different url rather than the visible url.
