I read that -> sets keys to values but I also know that => also sets keys to values in an array. I see the -> in loops like this foreach(loops as loop->black); and many other places.

=> is considered an array operator and is meant to be used with arrays
-> is an object operator and should be used in OOP (Object Oriented Programming) to call methods on objects.

class Products
{
public function getPrice()
{
// some code
}
}
$product = new Products;
$product->getPrice();
Last line of above code calls method named getPrice() on object named $product.

Kazimierz Matan
13,257 PointsCode after public function getPrice(), within brackets {}, is a body of getPrice method (function). It is executed every time you call this function, like $product->getPrice();.
