Overloading properties and methods in PHP - what is the reason?

Question

Is it possible to use overload only for the reasons associated with using only nice features? :)

For instance:

echo $store->product->getPrice($currency);

• product will call __get, then __getObject ('product'), which makes the magik material and returns the current product, which is considered as an object (it is created if this is the first call)

echo $store->product('dog')->getPrice($currency);

• productwill call __call here , then __callObject ('product', ...) ...

---

An alternative without overload would be:

if(!$store->product)
  $store->product = new Product();

 echo $store->product->getPrice($currency);

and

$product = new Product('dog');
echo $product->getPrice($currency);

I really like overloading because I can get a good API for my classes. But the disadvantage is that overloaded material is 15 times slower than calling properties / methods directly.

Is it possible to use such an overload?

Payouts are ensured by observing the principles of object-oriented design. The first example allows you to freely bind by creating a product object from a factory. For more on OO design principles, see SOLID and GRASP
