make use of search results from public search engines

By specifying the following URL, you can use Google to search some specific websites, "www.php.net" in this case, by providing certain keywords, "zend optimizer" in this case. http://www.google.com/search?q=zend+optimizer+site:www.php.net Now, I'd like to buildup a search interface (a text box) for user to do the above search and have the results displayed on MY WEBSITE. How do I do that? I tried the following script, but it doesn't work. :-( <? function PostToHost($host, $path, $referer, $data_to_send) { $fp = fsockopen($host,80); fputs($fp, "GET $path HTTP/1.1\n"); fputs($fp, "Host: $host\n"); fputs($fp, "Referer: $referer\n"); fputs($fp, "Content-type: application/x-www-form-urlencoded\n"); fputs($fp, "Content-length: ".strlen($data_to_send)."\n"); fputs($fp, "Connection: close\n\n"); fputs($fp, $data_to_send); while(!feof($fp)) { $msg .= fgets($fp, 128); } return $msg; fclose($fp); } PostToHost("www.google.com","/search","http://www.google.com","q=zend+optimizer+site:www.php.net"); echo $msg; ?> Thanks.
