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]
Regards,
Sascha
