Note that an exception's properties are populated when the exception is *created*, not when it is thrown.  Throwing the exception does not seem to modify them.

Among other things, this means:

* The exception will blame the line that created it, not the line that threw it.

* Unlike in some other languages, rethrowing an exception doesn't muck up the trace.

* A thrown exception and an unthrown one look basically identical.  On my machine, the only visible difference is that a thrown exception has an `xdebug_message` property while an unthrown one doesn't.  Of course, if you don't have xdebug installed, you won't even get that.

when you are using xdebug, exceptions message will never be shown if you use any encoding different than UTF-8, so if you are using any database with translated messages like oracle, you should ALWAYS, always, throw a exception like this

throw new Exception(utf8_encode($message),$code), character like ã,é,ç, will make the exception message fail to be shown, if you are not using xdebug ( I do think you should at least try), this code will not affect your page.
