What are the advantages of using database IDs over session IDs to uniquely identify users in PHP applications?

Using database IDs to uniquely identify users in PHP applications offers several advantages over session IDs. Database IDs are persistent and unique for each user, ensuring consistent identification even if the session expires or is reset. They also allow for easier integration with databases and can be used for more complex data retrieval and manipulation. Additionally, using database IDs can enhance security by reducing the risk of session hijacking or manipulation. 

// Assuming $user_id is the database ID of the current user
$user_id = $_SESSION['user_id'];

// Retrieve user information using the database ID
$query = "SELECT * FROM users WHERE id = $user_id";
// Execute the query and fetch user data
