Description:
------------
I made a class that has a public function. If I assign a value to the function, PHP will allow to assign a value, and if I started to retrieve the value, it will return the value.

Reproduce code:
---------------
/*example*/
class Field {
   function GetField(){
      
   }
}

/*usage*/

$m_Field=new Field;
$m_Field->GetField="Hello";
echo $m_Field->GetField; /* please note the absence of parenthesis*/

Expected result:
----------------
it should produce a fatal error, concerning the assigning of the data in a function;

Actual result:
--------------
Hello

/* returns the value you have set.*/
