All objects can have a special built-in method called a ‘constructor’. Constructors allow you to initialise your object’s properties (translation: give your properties values,) when you instantiate (create) an object.
Note: If you create a __construct() function (it is your choice,) PHP will automatically call the __construct() method/function when you create an object from your class.
The ‘construct’ method starts with two underscores (__) and the word ‘construct’.
