Código PHP:

  <?php  
 
    //Here request user actions in the web 
    //And process to clean information 
    class UserInfo { 
        var $Counternotice;

        var $CounterDate;     
        var $CounterUser;

        function UserInfo() { 
        //Get username name if user has logged in 
        global $loggedInUser; 
        if(!isUserLoggedIn()) { $this->CounterTempUser = "Guest";  
        } else { $this->CounterTempUser = $loggedInUser->display_username; 
        } 
         
        $this->Counternotice         = "User action info cleaned correctly";                 
        $this->Counterip             = htmlentities($_SERVER['REMOTE_ADDR']);         //get visitor ip

        } 
        function show() {echo "$this->Counternotice"; echo "<br />";} 
    }
