How can PHP developers effectively handle dynamic expansion of user rights in a role-based access control system?

When dealing with dynamic expansion of user rights in a role-based access control system, PHP developers can create a flexible database structure to store user roles and permissions. By allowing for dynamic assignment of permissions to roles and users, developers can easily adapt to changing requirements without needing to modify the codebase. Additionally, using a middleware or authorization layer can help streamline the process of checking user permissions. 

// Example of dynamically assigning permissions to roles and users in PHP

// Database structure for roles and permissions
// roles: id, name
// permissions: id, name

// Assign permissions to roles
$adminRole = Role::findByName('admin');
$adminRole->givePermission('create_post');
$adminRole->givePermission('edit_post');

$editorRole = Role::findByName('editor');
$editorRole->givePermission('edit_post');

// Assign roles to users
$user = User::find(1);
$user->assignRole('admin');

// Check user permissions
if ($user->hasPermission('create_post')) {
    // Allow user to create a post
} else {
    // Deny access
}
