How Do I Create a Website That Displays User-Submitted Text for Future Visitors?

Think about what happens if multiple users submit text at the same time. All those users might see the same text if the process isn't handled correctly. You could write to a file instead of setting up a database, but you'll still need a method to manage the submissions securely.

If you get this working, remember to implement some security measures! It's crucial to disable links in the text and have some form of bot protection to prevent misuse.

You should keep a single record in a persistent database and allow new submissions to overwrite whatever was previously there. This way, only the latest submission will be displayed.

To start, you'll want to add submitted text to a persistent database. While using a server-side language like PHP to create a `.txt` file might be the easiest way, it's not the best practice. When visitors submit text via a `POST` form, PHP can read from this file and display the content. However, if you're serious about your site, consider using a more robust database system as your traffic grows.
