echo $this->name;
public relates to the visibility of the property (public - can be seen
by all, protected - can only be seen by this class and sub-classes and
private - can only be seen by this class).

this should be:
function printMember(){
echo 'Name: ' . $this->name;
echo 'Alter: ' . $this->alter;
echo 'Gehalt: ' . $this->gehalt;
echo 'Abteilung: ' . $this->abteilung;
}

Hi Alex,

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

Hello,
i want to use the php APC Functions.
I am using xampp server and latest php.
The Windows dll for APC is in the extensions directory and the
extension is configured in the php.ini.
However, i still get an error that php does not find the fuction apc_add:
$myvar = 'hell world';
$stored = apc_add('myvar',$myvar);
if($stored){
echo 'Variable wurde gecached';
}
else{
echo 'Variable wurde nicht gecached';
}
Thank you
Alexander
