problem with using external variable inside class

I have following code:

$externVar=10;
class Aclass
{
public $a;
function __construct($a)
{
$this->a=$a;
}
public function fun()
{
echo "-->$externVar<--
";
}
}
$obj=new Aclass('sth');
$obj->fun(1);
?>

and on a page I see only --><-- instead -->10<-- which I expect. I
couldn't understand why variable $externVar defined outside class
definition is invisible inside this class. How to use such variables
inside the class definition?

Or, better yet, pass it to the function. Globals should be used seldom,
if at all.

In addition to the other replys: You should also fix your error
reporting and set it to E_ALL|E_STRICT in your php.ini, because PHP
would have shown you a notice ("Undefined variable ...").
