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
