Hi,
do
--
echo $data[0]*$data[1]);
return ($data[0]*$data[1]);
--
i think its empty.
In the first place, i thought it was maybe impossible to call a
class-functions in your constructor. (Cause the class function don't exists
at the moment you call your constructor).
But the code below showed it isn't that:
limiet=$this->test2();
}
function test2()
{
return 5;
}
function test3()
{
echo 'Limiet:'.$this->limiet;
return $this->limiet;
}
}
$TEST= new test();
echo 'Limiet:'.$TEST->test3();
?>
>global $WORKDIR;
NOTE: You should prefer $GLOBALS['WORKDIR'];
