DevShed continues their series looking at exceptions in PHP with this second part focusing on throwing and handling customized exceptions in your PHP5 application.

While the built-in exception system that comes bundled natively with PHP 5 is usually good enough to handle errors and other critical conditions during the execution of a given web application, it's worthwhile to mention that there are a number of additional cases where it is necessary to implement an exceptions system that can handle different failures in a more specific way.

They show how to trigger some basic custom exceptions and detail the creation of a class to handle catching these exceptions in a bit more OOP kind of way.
