The idea is simple. When you send "subscribe" to the bot, the bot server would add a record according to the sender_id to their database or memory , then the bot server could set a timer to distribute the news messages to those sender_id who have subscribed for the news.

don't know which part you want. For the bot receiver and sender there are some sample codes written in php, you can search and reach them through internet. For the daily notification, you can use `crontab` to schedule a task, select the sender_id in your database and send the message to the users. – Hui-Yu Lee Jun 26 '16 at 12:38

Hi Thanks brother for crontab information.I am working to following link [https://gist.github.com/visitdigital/58c71acb123870d1ac2ec714d7536587](https://gist.github.com/visitdigital/58c71acb123870d1ac2ec714d7536587). From this link, you will show "The message you want to return" [line number 30]. For example, how i send daily this message automatic to user like cnn by php. – Rubel Khan Jun 27 '16 at 08:04
