Where in the manual do you see this?

besides dangerous code if you find yourself doing this, you probally aren't
designing it correct. Your creating a static method of a class to access local
properties of another class thru the use of $this. If you want a way to access
member variables from a class in a static method, pass the object refrence into
the method.
Class foo {
function bar($obj) {
echo $obj->param;
/* $this should referr to the foo refrence, not another class refrence
*/
}
}
Class MyObject {
var $param;
function MyObject($param) {
$this->param = $param;
foo::bar($this);
}
}
