DevShed has posted the third part of their series looking at the creation of dynamic twitter signatures. These signatures are the sort of badges you'd see on a site with the user's latest tweet and their photo.

In the third installment in this series, I will be demonstrating how to add proper object-oriented error handling to the SignatureImage class.

They've built up the class to take in a twitter username and, via a cURL request pull in both the account's avatar and latest tweets. If something goes wrong, though, the class needs to be modified to handle it. They show how to add in try/catch handling with an error handler method in the class to work with the error's result.
