what's piece of advice on exception naming these days ? standard (java-style, old?) convention keep them @ root of namespace exception suffix: example\project\configurationexception symfony splits them purpose/components ( source ): example\project\user\banneduserexception example\project\graphs\notenoughdataexception facebook store them , keep exception suffix classes: facebook\exceptions\facebooksdkexception.php ( source ) braintree keep exceptions inside exception folder: braintree\exception\notfound ( source ) stripe has ditched entirely word exception in sdk , keep them inside same folder: stripe\error\invalidrequest . ( source ) there seems as ways there's developers out there... there written convention or what's trend out there used of ? also, set error code part of exceptions ? if so, how manage code ? i've got bunch of constants in example\project\errors , braintree does .
