OK. Things to take into consideration are: - If you use PEAR_Error, you add an external dependency to your package whereas exceptions are bundled in PHP5. I have had some requests for a PEAR free HTML_QuickForm, so exceptions are interesting in this case. - Returning a PEAR_Error object is IMO heavier than throwing an exception because of all the overhead it adds. I would be interested to know how many people know about exceptions and use them in their code already and what for.
