Definition of an class method
A class method/functions is the behavior/functionality of a class i.e. they provide the necessary code for the class in which it is defined. Examples could be a saveCustomer() method in the class Customer or a printDocument() in the Document class.

Methods act (perform operations) on the data members of the class and can be declared as private or public. A class method is exactly similar to PHP functions, it’s just that class functions are declared inside classes and accessed using the -> (arrow operator / dereferencing operator).

This tutorial will teach you how and when to use the magic method __autoload().

The magic method __autoload() function is a convenience that allows you to use classes without having to explicitly write code to include them.

The magic method __autoload() is not included in your class definition as this is to be called once in a script. The best place to put the autoload() file is in your configuration file which is loaded in all your other scripts.
