after looking back over your situation, which looks strange, why not use
composition at this level,
// note untested, may have some syntax errors
class B
{
private $a = null;
public function __construct(A $a)
{
$this->a = $a;
}
public function swapA(A $a)
{
$this->a = $a;
}
// proxy any calls to A which you would like to appear transparent
public function __call($method, array $args)
{
return call_user_func_array(array($this->a, $method), $args);
}
// note requires 5.3
public function __callStatic($method, array $args)
{
return call_user_func_array(array($this->a, $method), $args);
}
}
$a = new A();
$b = new B($a);
// some code ..
$anotherA = new A();
// some more code
$b->swapA($anotherA);
