What best practices should be followed when implementing user groups to grant access for DHCP management via PHP?

To implement user groups for granting access to DHCP management via PHP, it is important to follow best practices such as using role-based access control, validating user permissions before allowing access, and securely storing user group information. This can help ensure that only authorized users have the necessary permissions to manage DHCP settings.

// Check if user belongs to the DHCP management user group
$userGroups = ['admin', 'dhcp_manager']; // Define user groups with DHCP management access
$user = 'current_user'; // Get current user

if (in_array($user, $userGroups)) {
    // Allow access to DHCP management functionality
    echo "You have access to DHCP management";
} else {
    // Deny access if user does not belong to DHCP management user group
    echo "You do not have access to DHCP management";
}
