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
