我正试图从谷歌刮网址使用的是在代码中提供的呆子。
现在我正在使用cURL，但它说“curl_init（）在未定义的函数中”
到目前为止，我得到了：

//This is the Pattern for URL finding
$pattern = "~^(http|ftp)(s)?\:\/\/((([a-z0-9]{1,25})(\.)?){2,7})($|/.*$)~i"; 
//Enter your dork here.
$dork = "inurl: login.php";
//Set the Useragent
$ua = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311";
//Initialize cURL
$ch = curl_init();
$url = "http://www.google.com/search?q=".$dork;
$timeout = 10;
curl_setopt($ch,CURL_OPT, $url);
curl_setopt($ch,CURLOPT_USERAGENT,$ua);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);

$exec = curl_exec($ch);
$contents = curl_getinfo($ch);
//curl_close($ch);

//Set empty url array
$urls = array();
//Find urls on page you just grabbed ^
preg_match_all($pattern, $contents, $matches);

//Assign the urls to the empty array urls
    foreach ($matches[0] as $match)
    {
        $urls[] = "{$match}";
    }

//Remove any duplicates in url array
$vurls = array_unique($urls);
//take out spaces
$urlStr = implode("", $urls);

//count number of unique urls
$count = count($vurls);

//Writing to text file
$fh = fopen('wp.txt', 'w');
fwrite($fh, $urlStr);
fclose($fh);

//Echoing # of urls found.
echo "Done. Found {$count} sites.\n";

我不知道出了什么问题，我试图让它刮多页。但我想知道我该如何处理这件事。
如果有人能给我指出正确的方向，那将是非常有帮助的，我不需要填鸭式的喂养。
