Question

我试图让Telegram机器人向一个组发送消息，而不需要用户发出消息来触发它。更具体地说，我正在尝试设置生日提醒，其中机器人查询数据库，将条目与当前日期进行比较，并播放生日快乐＆＃34;组中的消息。如上所述，我想通过一个cronjob来实现，每天打开PHP脚本并让机器人播放它。

我的问题是我检查了所有Telegrams文档和演示代码（https://core.telegram.org/bots/samples），但所有这些都基于用户通过发送消息来触发机器人。

我的问题是，如果有人已经能够实现类似的功能并且可以帮助我扩展我的代码吗？可能值得一提的是，Bot已经集成到群聊中，我有一个聊天ID，机器人可以将聊天目标作为目标。我的代码如下（我必须承认我从演示示例中复制了它）：

Telegram Bot发送消息而不需要消息来触发它
