Bug description: Recursive call to setter "blocks" the property
Description:
------------
In the following example, the __setter invoked by $x->a = "g1"; statement
tries to write to "a" property again by $this->a = "a"; statement in the
switch. This latter access is correctly considered to be recursive and
thus treated as assignment to $this->a and not as a recursive call. That's
ok. However, after returning from the __setter and when invoking it again
by $x->b = "g2"; the $this->a = "b"; should call the __setter because we
it is not a recursive call ("b" was accessed, not "a"). Hence $this->a =
"b"; should invoke __setter in this case. And that doesn't happen.
Reproduce code:
---------------
class C
{
function __set($f,$v)
{
echo "set('$f','$v')\n";
switch ($f)
{
case "a": $this->a = "a"; break;
case "b": $this->a = "b"; break;
}
}
}
$x = new C;
$x->a = "g1"; // this blocks "a" on $x forever
$x->b = "g2";
Expected result:
----------------
set('a','g1')
set('b','g2')
set('a','b')
Actual result:
--------------
set('a','g1')
set('b','g2')
