What are the potential pitfalls of using elseif statements in PHP, especially in the context of user authentication?

Potential pitfalls of using elseif statements in PHP for user authentication include the possibility of creating complex and hard-to-maintain code, as well as the risk of overlooking certain conditions or introducing bugs due to the nested nature of elseif statements. To address this, it is recommended to use a switch statement instead, which can provide a more structured and readable way to handle multiple conditions in user authentication logic. 

// Example of using a switch statement for user authentication
$userRole = 'admin';

switch ($userRole) {
    case 'admin':
        // Code for admin user authentication
        break;
    case 'user':
        // Code for regular user authentication
        break;
    default:
        // Code for handling other user roles or unauthorized access
        break;
}
