Bug description: Assignment operators yield wrong result with __get/__set
Description:
------------
When there is a function on the right-hand side of an assignment operator
expression, and the variable is to be accessed via __get/__set, the
operation yields wrong results.
Reproduce code:
---------------
class Container
{
public function __get( $what )
{
return $this->_p[ $what ];
}
public function __set( $what, $value )
{
$this->_p[ $what ] = $value;
}
private $_p = array();
}
$c = new Container();
$c->a = 1;
$c->a += 1;
print $c->a; // --> 2
print " - ";
$c->a += max( 0, 1 );
print $c->a; // --> 4 (!)
Expected result:
----------------
2 - 3
Actual result:
--------------
2 - 4
