Crap, I didn't mean to send that. This is the actual code:
a = $a;
}
if(!is_null($b))
{
$this->b=$b;
}
}
function printAB() {
echo $this->a." ".$this->b."\n";
}
}
$inst1 = new TestClass(3,50);
$inst2 = new TestClass();
$inst1->printAB();
$inst2->printAB();
?>

After cleaning up the code (I think the mail system might have stuck
in some weird characters, this is what I got:
a = $a;
}
if(!is_null($b))
{
$this->b=$b;
}
}
public function printAB() {
echo $this->a." ".$this->b."\n";
}
}
$inst1 = new TestClass(3,50);
$inst2 = new TestClass();
$inst1->printAB();
$inst2->printAB();
?>
Outputs:
3 50 20 10
as you expect. What is the question?

It'd be great if you provided the output you are getting.
