1.先获取公众号的access_token

private $appid='';
private $secret='';
private function getAccessToken() {
        // access_token 应该全局存储与更新，以下代码以写入到文件中做示例
        $data = S('access_token');
        if ($data['expire_time'] < time()) {
            // 如果是企业号用以下URL获取access_token
            // $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret";
            $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$this->appid."&secret=".$this->secret;
            $res = json_decode($this->http_curl($url),true);
            $access_token = $res['access_token'];
            if ($access_token) {
                $data['expire_time'] = time() + 7000;
                $data['access_token'] = $access_token;
                S('access_token',$data);
            }
        } else {
            $access_token = $data['access_token'];
        }
        return $access_token;
    }

2.再根据"https://api.weixin.qq.com/cgi-bin/user/info?access_token=".$accessToken."&openid=".$openid；调用curl，根据返回的结果集里的subscribe的状态进行判断

 1     public function attention(){
 2         $openid=$_SESSION['weinfo']['openid'];
 3         // 获取公众号的access_token，此access_token不是用户授权后的access_token
 4         $accessToken = $this->getAccessToken();
 5         $subscribe_msg = "https://api.weixin.qq.com/cgi-bin/user/info?access_token=".$accessToken."&openid=".$openid;
 6         $subscribe_info = $this->http_curl($subscribe_msg);
 7         $subscribe_info = json_decode($subscribe_info);
 8         if($subscribe_info->subscribe){
 9             $msg['status']=1;
10         }else{
11             $msg['status']=0;
12         }
13         return $msg;
14     }
