This brings us back to an old problem the severity levels are inconsistent. And further more we decided some time back that E_ERRORs shouldn't be converted to exceptions because of a few E_ERRORs that might not be continuable. From my point of view we should do two things: 1) convert the non continuable E_ERRORs to a higher severity (if there are any at all) 2) Use exceptions when a ctor needs to advertise its failure and in other places where exceptions are really usefull. Too much exception is a bad thing anyway. -- Best regards, Marcus mailto:helly@php.net
