Extra parameters for strtoupper(), strtolower()

string strtoupper(string string [, int start [, int length]]) string strtolower(string string [, int start [, int length]]) The additional parameters would work in much the same fashion as substr(). I've implemented it in the latest cvs just for the hell of it. Am I the only one who thinks this is even remotely useful? It isn't a big thing, but it's a lot easier to have this available than to chop up a string with substr() and then capitalize what you want. A pretty useless feature, I guess. Obviously, I'm pretty bored right now. J
