Brandon Savage's Blog:
Exceptional PHP Nesting Exceptions In PHP
November 12, 2009 @ 12:43:48

Brandon Savage continues his introductory series on exception handling in PHP with this new post to his blog. This time the focus is on methods for nesting exceptions.

In the last two entries we have talked about the concept of layer abstraction: that is, that exceptions should not be allowed to pass out of one layer and into another. So, when an exception is raised in the database layer it should be caught in the controller. But how do we go about making sure that exceptions raised in the database layer are properly recorded and processed, ensuring that we have error logging and don't simply silence our exceptions?

He looks first at general exception nesting then at extending the base Exception class to write more nested code (inside a class). He also touches on the nested exceptions that were included in the latest release of the PHP 5.3 series.
