addRecipes challange question

Hey György, nice to see how far you progressed.

Here is the addRecipes() method you referred to.

class RecipeCollection
{
    private $recipes = array();

    public function addRecipes(array $recipes)
    {
      array_push($this->recipes, $recipes);
    }
}

Within the addRecipes you are using array_push(). This function takes anything and adds it to the end of the array.

The problem is that you are pushing the $recipes array that you passed as an argument to the end of the private $recipes array that serves as your collection. Thus making a two dimensional array.

The solution you are looking for is a way to merge the array you passed to the addRecipes() function to the existing $recipes array in your RecipeCollection. Make sure it only yields instances of your Recipe class.
