Are there any best practices for handling user permissions and rights in PHP applications?

When handling user permissions and rights in PHP applications, it is important to follow best practices to ensure security and proper access control. One common approach is to use role-based access control (RBAC) where users are assigned roles with specific permissions. This allows for easier management of permissions and ensures that users only have access to the resources they need. 

// Example of role-based access control (RBAC) implementation in PHP

// Define roles and their corresponding permissions
$roles = [
    'admin' => ['manage_users', 'manage_posts', 'manage_settings'],
    'editor' => ['manage_posts'],
    'user' => ['view_posts']
];

// Check if user has permission to access a specific resource
function hasPermission($userRole, $requiredPermission) {
    global $roles;
    
    if (isset($roles[$userRole]) && in_array($requiredPermission, $roles[$userRole])) {
        return true;
    }
    
    return false;
}

// Example usage
$userRole = 'admin';
$requiredPermission = 'manage_users';

if (hasPermission($userRole, $requiredPermission)) {
    echo 'User has permission to manage users.';
} else {
    echo 'User does not have permission to manage users.';
}
