微信公众号/服务号 标签管理

使用标签的原因是为了用个性化菜单，但是发现有时候就可以，有时候就24小时，48小时过去了还是没有变。根据微信的说明公众号每5分钟就会获取一次用户信息是否有更新，但是这个又是为什么呢

用户标签单独弄了一个类UserTag，框架是ThinkPHP 5.0.10

<?php
namespace app\common;

use Fuwuhao\API;

class UserTag {
    private $tagId,
        $accessToken,
        $tagName,

  function __construct(string $accessToken){
    $this->accessToken = $accessToken;
  }
   /**

   *
   * @param $tagid
   *
   * @return $this
   */
  public

    $this->tagId = $tagid;

    return $this;
  }

  /**

   *
   * @return $this
   */
  public

    $this->tagName = $tagname;

    return $this;
  }
  /**

    # 判断是否添加成功
    if(array_key_exists('errcode', $rst) && $rst['errcode'] != 0) # 出错了

完了回答刚开始的问题了，

微信开发者页面有提示，只不过没有注意看

个性化菜单接口支持用户标签，请开发者注意，当用户身上的标签超过1个时，以最后打上的标签为匹配

在个性化菜单接口说明中有
