PHP微信公众平台开发高级篇—自定义菜单 （根据慕课网上的视频教程编写）
一、说明
1、根据慕课网上的教程为基础，这是前两个基础教程：
PHP实现微信公众平台开发—基础篇：https://www.imooc.com/video/9316
PHP实现微信公众平台开发—提升篇 ：https://www.imooc.com/video/10231
2、慕课上视频讲解用的是thinkphp早期版本，我用的是thinkphp3.2.3版本。可以看慕课视频进行学习，讲的比较详细

3、代码亲测有效
二、IndexController控制器代码
namespace Weixin\Controller;
use Think\Controller;
class IndexController extends Controller{
public function __construct(){
}//可以不写
public function index(){
//获得参数 signature nonce token timestamp echostr
$nonce = $_GET['nonce'];
$token = 'weixin';
$timestamp = $_GET['timestamp'];
$echostr = $_GET['echostr'];
$signature = $_GET['signature'];
//形成数组，然后按字典序排序
$array = array();
$array = array($nonce, $timestamp, $token);
sort($array);
//拼接成字符串,sha1加密 ，然后与signature进行校验
$str = sha1( implode( $array ) );
if( $str == $signature && $echostr ){
//第一次接入weixin api接口的时候
echo $echostr;
exit;
}else{
$this->definedItem();
$this->reponseMsg();
}
}
// 接收事件推送并回复
public function reponseMsg(){
//1.获取到微信推送过来post数据（xml格式）
//$postArr = $GLOBALS['HTTP_RAW_POST_DATA'];//php7开始不支持
$postArr = file_get_contents("php://input");
//2.处理消息类型，并设置回复类型和内容
$postObj = simplexml_load_string( $postArr );
//判断该数据包是否是订阅的事件推送
if( strtolower( $postObj->MsgType) == 'event'){
//如果是关注 subscribe 事件
if( strtolower($postObj->Event == 'subscribe') ){
/* //回复用户消息(纯文本格式)
$toUser = $postObj->FromUserName;
$fromUser = $postObj->ToUserName;
$time = time();
$msgType = 'text';

$content = '欢迎关注放哥的微信公众账号';
$template = "

// 回复单文本

//回复微信用户的关注事件
