PHP クロール Web ページのコード例

//PHP(前提是装了curl):
$ch =curl_init();
curl_setopt ($ch, CURLOPT_URL, "http://www.xxx/");
curl_setopt ($ch, CURLOPT_REFERER) , "http://www.xxx/");
curl_exec ($ch);
curl_close ($ch);

//PHP(不装curl用sock)
$server = 'blog.qita.in' ;
$host = 'blog.qita.in';
$target = '/xxx.asp';
$referer = 'http://blog.qita.in/';      // Referer
$port = 80;
$fp = fsockopen($server, $port, $errno, $errstr, 30);
if (!$fp)
{
 echo "$errstr ($errno)< br />n";
}
else
{
 $out = "GET $target HTTP/1.1rn";
 $out .= "ホスト: $hostrn";
 $out .= "Cookie: ASPSESSIONIDSQTBQSDA=DFCAPKLBFICDAFMHNKIGKEGrn ";
 $out .= "リファラー: $refererrn";
 $out .= "接続: Closernrn";
 fwrite($fp, $out);
 while (!feof($fp))
 {
 echo fgets ($fp, 128);
 }
 fclose($fp);
}
