Error Handling Class - Any Recommendations?

Anyone recommend a good one? I am in need of the following features: 1) Catch any type of errors, 2) Actions like: Show on the screen, log on a file or database, or email, 3) Different actions for each error level/warning type, etc.. I have searched Hotscripts, but only found classes to control server errors, like 404 or 503. On Sourceforge, no projects with files, and Google returns me thousands of unrelated pages and I couldn't filter the results until they were satisfactory ;-) I understand PEAR has somekind of error control, and it's my current DB Abstraction Layer's choice. If there's a way to keep using PEAR to handle other errors, I would be very glad if someone could point me to any tutorial or documentation about how to do so, Thanks, -- Julio Nobrega.
