php 移动适配识别手机和电脑的类-百度终端适配封装类

今天用到了移动适配，百度移动端适配，为了能够准确的识别手机还是电脑，所以我们用了百度的终端适配服务，经过测试这个东西的准确率非常高，为了方便以后人的使用我就 把它封装成了一个类，就不必要再写那么多的代码，只需要你有一个百度的应用提取上边的client_id和client_secret就可以使用了！

<?php
/**
 *  Baiapt.class.php 百度移动终端适配类
 */
 class Baiapt{
    private $client_id;         //百度应用 duapp.com中申请添加应用 就可以获得API Key
    private $client_secret;     //对应的Secret Key
    private $grant_type = 'client_credentials';
    private $token;
    function __construct($client_id,$client_secret){
        $this -> client_id = $client_id;
        $this -> client_secret = $client_secret;
        $this -> token = $this ->gettoken();
    }

    //封装的https的post方法获得返回参数
    private function post($url,$post,$header="Content-type: text/xml"){
        $ch = curl_init($url);
        curl_setopt($ch ,CURLOPT_HEADER, $header);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch, CURLOPT_POST, 1);
        if(is_array($post)){
            $post = http_build_query($post ,'','&');
        }
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
        $content = curl_exec($ch);
        curl_close($ch);
        return $content;
    }

    //获取token的方法
    private function gettoken(){
        $post = array(
            'grant_type' =>$this->grant_type,
            'client_id' =>$this->client_id,
            'client_secret' =>$this->client_secret,
        );
        $result = $this->post('https://openapi.baidu.com/oauth/2.0/token',$post);
        $token = json_decode($result)->access_token;
        return $token;
    }

     public function Pcphone($useragent){
