prepare("DELETE FROM users WHERE id = ?"); $stmt->execute([$user_id]); // Redirect to the homepage header('Location: /my_app/home.php'); exit(); } ?>This code snippet shows how to delete a user account from a MySQL database using PDO. It first checks if the 'delete_user' button has been clicked, then gets the user ID from the form. Next, it connects to the database using PDO and deletes the user from the 'users' table. Finally, it redirects the user to the homepage. The package library that can be used for the User destroy app in PHP is the PHP Data Object (PDO) class library. It provides a database abstraction layer that allows developers to write database code that is portable between different database systems. Additionally, it provides a secure and efficient way to interact with databases, preventing common security issues like SQL injection.
