Answer 1

If using Curl in php...

function disguise_curl($url) 
{ 
  $curl = curl_init(); 

  // Setup headers - I used the same headers from Firefox version 2.0.0.6 
  // below was split up because php.net said the line was too long. :/ 
  $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,"; 
  $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; 
  $header[] = "Cache-Control: max-age=0"; 
  $header[] = "Connection: keep-alive"; 
  $header[] = "Keep-Alive: 300"; 
  $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; 
  $header[] = "Accept-Language: en-us,en;q=0.5"; 
  $header[] = "Pragma: "; // browsers keep this blank. 

  curl_setopt($curl, CURLOPT_URL, $url); 
  curl_setopt($curl, CURLOPT_USERAGENT, 'Googlebot/2.1 (+http://www.google.com/bot.html)'); 
  curl_setopt($curl, CURLOPT_HTTPHEADER, $header); 
  curl_setopt($curl, CURLOPT_REFERER, 'http://www.google.com'); 
  curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate'); 
  curl_setopt($curl, CURLOPT_AUTOREFERER, true); 
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
  curl_setopt($curl, CURLOPT_TIMEOUT, 10); 

  $html = curl_exec($curl); // execute the curl command 
  curl_close($curl); // close the connection 

  return $html; // and finally, return $html 
} 

// uses the function and displays the text off the website 
$text = disguise_curl($url); 
echo $text; 
?>
