Are there any best practices for handling user authentication and access control in PHP applications?

User authentication and access control are crucial aspects of web application security. It is important to use secure password hashing techniques, such as bcrypt, to store user passwords safely. Additionally, implementing role-based access control (RBAC) can help manage user permissions effectively. 

// Example of secure password hashing using bcrypt
$password = "password123";
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

// Example of verifying a password
$entered_password = "password123";
if (password_verify($entered_password, $hashed_password)) {
    echo "Password is correct";
} else {
    echo "Password is incorrect";
}

// Example of role-based access control (RBAC)
$user_role = "admin";

if ($user_role == "admin") {
    echo "You have admin privileges";
} else {
    echo "You do not have admin privileges";
}
