How can users be managed across multiple PHPBB forums running on the same database?

To manage users across multiple PHPBB forums running on the same database, you can create a centralized authentication system that checks user credentials against the shared database. This way, users only need to log in once to access all forums. You can achieve this by modifying the login process in each forum to query the shared database for user credentials. 

// Example code snippet to authenticate users against a shared database

// Connect to the shared database
$shared_db = new mysqli('localhost', 'username', 'password', 'shared_database');

// Get user credentials from the login form
$username = $_POST['username'];
$password = $_POST['password'];

// Query the shared database to check user credentials
$query = "SELECT * FROM users WHERE username = '$username' AND password = '$password'";
$result = $shared_db->query($query);

// If user credentials are valid, log the user in
if ($result->num_rows > 0) {
    // Perform login actions
} else {
    // Display an error message
}

// Close the database connection
$shared_db->close();
