PHP Object-Oriented PHP Basics Building the Recipe Associative Arrays

How to pass a value to a second optional parameter?

ie.

$recipe1->addIngredients("egg", , "tsp");

1 Answer

Since the default value of amount is null, you could pass in null as the value for amount: $recipe1->addIngredients("egg", null, "tsp");

You could also use named parameters: $recipe1->addIngredients("egg", measure: "tsp");
