解析php通过cookies获取远程网页的指定代码

复制代码 代码如下:

  function Steal($url, $post_data = ""){

  //$header[] = "Accept: text/vnd.wap.wml,*.*";

  $user_agent = "Mozilla/4.0";

  $follow_loc = 1;

  $cookie_file ="./tmp/cook.txt";

  $ch = @curl_init();

  @curl_setopt($ch, CURLOPT_URL, $url);

  @curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);

  @curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);

  @curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);

  @curl_setopt($ch, CURLOPT_HEADER, $header);

  @curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

  @curl_setopt($ch, CURLOPT_FOLLOWLOCATION, $follow_loc);

  @curl_setopt($ch, CURLOPT_TIMEOUT, 1000);

  if (trim($post_data)!= "") {

  @curl_setopt($ch, CURLOPT_POST, 1);

  @curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

  }

  $result = @curl_exec($ch);

  @curl_close($ch);

  return $result;

  }

  //获取网页代码的方法

  function Cut($file,$from,$end){

  $message=explode($from,$file);

  $message=explode($end,$message[1]);

  if ($message[0] == "")

  {

  $message[0] = "<font color= '#ff0000'>无法获取内容</font>";

  }

  return $message[0];

  }

  //截取代码的方法
