Object Constructors

A constructor is a special object method that gets called automatically each time a new instance of a class is instantiated.
Constructors are used to perform any initialization tasks that need to be done before an object is ready to be used, such as providing default values for all of an object’s properties.
In PHP 5, constructors are known as magic methods and must be named __construct(). They are defined within a class definition just like any other object method.
Arguments are provided to an object’s constructor method by specifying them between the parentheses following the class name when an object is created using the new keyword:
$person1 = new Person(‘Joe’, ‘Smith’);
A class is not required to have a constructor method.
Unlike other programming languages, only one constructor method can be defined per PHP class.
