as Richard pointed out, you were not pointing at the class member's name but to the visibility of the variable instead; to give you a start, this is how your class should look like (but I would really advise to have a look at Richard's link to get a better understanding of class usage and OOP):

[CODE]
class Mitarbeiter{
    // use private if you are using getter methods to access members
    private $name = 'meier';

    public $alter = '50';
    public $gehalt = '2000';
    public $abteilung = 'programmierung';

    function get_name (){
        return $this->name;
    }

    function printMember(){
        echo 'Name: ' . $this->name . "<br />;
        echo 'Alter: ' . $this->alter . "<br />";
        echo 'Gehalt: ' . $this->gehalt . "<br />;
        echo 'Abteilung: ' . $this->abteilung . "<br />;
    }
}

$m = new Mitarbeiter();
$m->printMember();

// this would fail, because I changed the visibility of member 'name' from
// public to private
print $m->name;
// use a getter method instead:
print $m->get_name();

// this would work because the visibility is public, member is accessible from outside of the class
print $m->alter;

[/CODE]

Sascha
