PHP Bug Type: Feature/Change Request
Bug description: static calls and $this
Description:
------------
In static calls $this is set.
While in theory it might make sense to allow objects
of the same class (or derived class) to "use" this
feature, it's a potential pitfall and from my point
of view it's bug.
I think if a non static method is called statically
then $this can't be any object that hasn't been
created by this or a derive class.
No other language has such a "feature" :)
If it's not a bug, then read my bugreport as
"remove this feature".
If it's a bug, add a runtime checking for $this is object
created by same or derived class.
Reproduce code:
---------------
Example:
Noone can really say that this is "transparen" ok:
class Foo {
private $hallo="I am from Foo";
function dontCallMe() {
return $this->hallo;
}
}
class Bar {
public $hallo="I am from Bar";
function testMe() {
return Foo::dontCallMe();
}
}
$x=new Bar();
echo ($x->testMe()); // expected runtime error...
Expected result:
----------------
Runtime error.
Actual result:
--------------
output is: "I am from Bar"
This return the member var of Bar, what you would NEVER expect.
