Whether you're new to the language or to the more advanced features of it, you might find the magic methods a bit confusing at first. Thankfully, NETTUTS.com is here to help with this new tutorial on what they are and how to use them in your code.
PHP provides a number of 'magic' methods that allow you to do some pretty neat tricks in object oriented programming. These methods, identified by a two underscore prefix (__), function as interceptors that are automatically called when certain conditions are met. Magic methods provide some extremely useful functionality, and this tutorial will demonstrate each methodâ€™s use.
