On Monday, we talked about the basics of exceptions and how they are used in PHP (as well as in other object-oriented programming languages). As promised, today we are going to talk about extending the base exception class in PHP.
One of the things that you can (and should) do with PHP exceptions is extend them to suit your own purposes. While the base Exception class in PHP is neither abstract nor impossible to use on its own, extending exceptions give you a great amount of flexibility and power, particularly in three areas: customization, identification, and abstraction.
