PHP Get Object from Cache

Question

I'am using memcache to store PHP class object using serialize and unserialize. Is any way to get back original class object using new Method?

My example:

class Test
{
    public $id;

    public function __construct($id)
    {
        if (InCache($id)) {
            return unserialize(GetFromCache($id));
        } else {
            $this->id = $id;
            SaveToCache(serialize($this));
        }
    }
}

Calling:

$t = new Test(1);

If ID is in cache or NOT, I need back same output:

Test Object
(
  [id] => 1
)

Anybody can help?

in php you can't return in a __construct function

you could get the new Object from a Factory Funktion like this:

class Test
{
    public $id;

    protected function __construct($id)
    {
        $this->id = $id;
        SaveToCache(serialize($this));
    }

    public static function getNewObject($id)
    {
        if (InCache($id)) {
            return unserialize(GetFromCache($id));
        } else {
            return new self($id);
        }
    }
}

Calling:

$t = Test::getNewObject(1);

@Ondra There is no selfreplace function in php. That is correct.
