php实现登录tplink WR882N获取IP和重启的方法

<?php
// tplink wr882n 管理脚本
function getcontent($url)
{
  // 解悉url
  $temp = parse_url($url);
  $query = isset($temp['query']) ? $temp['query'] : '';

    'accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
    'cookie: authorization=basic ' . base64_encode("admin:admin"),  // 注意这里的cookie认证字符串
    "referer: http://{$temp['host']}/",
    'user-agent: mozilla/4.0 (compatible; msie 7.0; windows nt 5.1; sv1)',
    "content-length: 380",
    "connection: close"
  );
  $curl = curl_init(); // 启动一个curl会话
  curl_setopt($curl, curlopt_url, $url); // 要访问的地址
  curl_setopt($curl, curlopt_httpheader, $header); //设置头信息的地方
  curl_setopt($curl, curlopt_timeout, 60); // 设置超时限制防止死循环
  curl_setopt($curl, curlopt_header, 0); // 显示返回的header区域内容
  curl_setopt($curl, curlopt_returntransfer, 1); // 获取的信息以文件流的形式返回
  $content = curl_exec($curl); // 执行操作
  curl_close($curl);
  return $content;
