在PHP-JavaScript中实现消息传递服务

Question

I have a intranet web database application in a LAMP environment. I would like to implement an internal messaging service like e-mail but just for the users in my application. I don't want any code just the general idea on how can something like this be implemented. I'm not very strong in JavaScript but I always learn whatever I don't know.

Answer 1

1. make database table called messages. (id, body, time, author)
2. Make an HTML form with textarea and submit, action can be the same PHP page or other. (I prefare same page idea.)
3. once the form is submitted, sanitize data for database and create variable which will hold the text from the textarea.
4. insert this text in messages table.
5. then some JavaScript-PHP code which will display all the messages from the database below, next to or above the form. If you have any questions, feel free to ask!
