About Magic Methods and Predefined Constants in PHP

PHP provides a set of special predefined constants and magic methods to your programs. Unlike the constants you would set using define() , the value of the constants depend on where they are used in your code and are used to access read-only information about your code and PHP. The magic methods are reserved method names you can use in your classes to hook into special PHP functionality.
