$x does not exist until instantiation, so you should assign $y in the
constructor:
class MyClass2 {
var $x = 2;
static $y;
function __construct() {
$this->y = $this->x;
}
}
The same principle applies to the previous MyClass code, where $this->x
should be replaced by self::$x.

From http://www.php.net/manual/en/language.constants.php:
"Only scalar data (boolean, integer, float and string) can be contained in
constants."
