Jani Hartikainen has written up a new post looking at error handling in one of the more popular PHP frameworks - the Zend Framework.
In Zend Framework based applications, error handling is typically done using the error controller, but there are different ways to send the execution to it - some better than others. Let's look at some ways to trigger the error controller and how to have it handle different error conditions.
He walks through the steps to create the Error controller, change the front controller to use it and add in a few different kinds of actions to handle the various error types that might come up (like "page not found" or "not authorized"). Errors can then be forwarded to each of the actions by the resource the visitor errored from. Of course, he also mentions that exceptions can do something even better - handle the error without all of that messy forwarding around. (There's an example of that version too).
