我是靠谱客的博主超级小甜瓜，最近开发中收集的这篇文章主要介绍解析php通过cookies获取远程网页的指定代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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
