Description:
------------
If a static method is called from an objectcontext, $this is accessible from that objectcontext.
$this should be out of scop in the static method...

Reproduce code:
---------------
class static_class {
   function static_func() { echo $this->variable;  }
}

class testclass {
   function func() { static_class::static_func(); }
}
$x = new testclass();
$x->func();




Expected result:
----------------
<br />
<b>Fatal error</b>:  Using $this when not in object context in <b>[filename]</b> on line <b>2</b><br />

Actual result:
--------------
No output (thus no error)

Output with latest CVS:

PHP Notice:  Undefined property:  testclass::$variable in /home/jani/t.php on line 4

Still not fixed, it produces the wrong error. It should warn about $this, not about $variable.
I am cvsupping as we speak, but i assume thie following testcase still doesn't produce an error:

class static_class {
   var $variable="Variable in static_class.";
   function static_func() { echo $this->variable;  }
}

class testclass {
   var $variable="Variable in testclass.";
   function func() { static_class::static_func(); }
}
$x = new testclass();
$x->func();

You need to use 'static' in the function declaration
to make it work like you expect. (otherwise it behaves like in PHP4..)

static function static_func() { echo $this->variable;  }
