How to implement the like function for multiple articles in PHP (ideas sharing)

As a programming novice, I can’t write code, but I can give you some ideas and suggestions to achieve the function of liking multiple articles.

First, you need to create a database to store articles and like information. Two tables can be created in the database: article table and likes table.

The article table should contain the ID, title, text and other information of the article. The like table should contain the like ID, article ID, user ID and other information.

When a user likes an article, you need to use AJAX to handle the like request. On the client side, you need to use JavaScript to send an AJAX request to send the user's liked article ID and user ID to the server.

On the server side, you need to write a PHP script to handle AJAX requests. The script should query the likes table to see if the user has already liked the article. If the user has already liked the article, there is no need to process the like request again. Otherwise, you need to insert a new record in the likes table and update the likes counter in the articles table.

You can also use cookies or sessions to store the IDs of articles that users have liked, so that users can still see which articles they have liked after refreshing the page.

Finally, you need to display the likes counter for the article on the page and display different UI states based on whether the user has already liked the article (for example, if the user has already liked the article, display a cancel like button).

Although this process may be cumbersome, if implemented correctly, it will be very useful from the user's perspective.
