Re: PEAR.php to PHP5

I think a more progressive PHP5 solution would be to add that observer functionality into PEAR_Exception. And have the constructor signal observers. PEAR_Exception::addObserver('name', array($obj, 'methodName')); And then just throw new PEAR_Exception("Msg", ERR_CODE);

Attached (if it makes it through) is a simplified version of PEAR_Exception that has the functionlity mentioned. Note that the point of this is not address any compatibility (which I feel is unnecessary given that php4 packages have to be rewritten anyway), but rather to address missing features of Exception. I think Tobias was right (sorry for arguing, Toby); a PEAR_Exception base class could be quite useful -- as it will add missed features from PEAR_Error and play nice w/ non-PEAR code. This version handles nesting in addition to the observers. (Though I simplified & made all observers callbacks.) Hans
