oops problem

[Jaswinder]

hello friends i am new to oops.... what i am trying is put the value of a constant in a variable... but not getting any output

 

code :-

 

<?php
class visible
{
    const a='Hello';
}
class check extends visible
{
    private $c;
    public function c()
    {
        $this->c=self::a;
    }
}
$d=new check;
echo $d->c();
?>

 

is it possible to inherent a constant ??

What do you expect to be echo'd? All the method "c" is doing is assigning a value to a variable. It isn't returning anything.
