But I would use it as a postfix like this: PEAR_Something_Interface >This way, I could solve all of my concerns about PEAR_Exception with an >interface like so: > >interface PEAR_InterfaceMultiError extends SPL_Iterator >{ > public function errorCount(); > public function addError(PEAR_Exception $e); > public function addWarning(...); > public function iterator functions that allow foreach/while >} > >and then users can do this: > >if ($e instanceof PEAR_InterfaceMultiError) { > foreach ($e as $error) { > // do stuff > } >} NB: Personally, I find it a bit silly to use instanceof for an interface when a class actually *implements* one or more interfaces, but apparently PHP5 allows it... I think I will wait until I see some code before giving you an opinion about this. Is this going to duplicate PEAR_ErrorStack features for PHP5 PEAR_Exception only ? Bertrand Mansion Mamasam
