== How is an Object Created from a Class? ==

The process of creating an object from the class 'blueprint' is called instantiation. Essentially, you instantiate an instance of the class and give that instance a name by which you will refer to it when accessing members and calling methods. You can create as many object instances of a class as you desire. Objects are instantiated using the ''new'' keyword. For example, to create an instance of a class called ''bankAccount'' we would write:

The ''method_exists()'' function, when passed an object pointer and method name as arguments, will return a true or false value indicating the existence of the method.
