如何显示最新的4条新闻？

I have a news script. This script works like the following:

1. I enter the news details from a form
2. The news is inserted into the database
3. The news is displayed to the visitor

I need to display the latest 4 news only, not all news entries. How can I do this?

Make your query like this:

SELECT * FROM news ORDER BY news_id DESC LIMIT 4

where news_id is the primary key of your news table.
