Using lots of globals will make that harder, since it will mean that you cannot simply lift that function out and drop it into some other chunk of code without making sure that the new global space contains all those globals, and that they contain what you expect. This is called 'tightly-coupled' code. It's just harder to reuse. 'Loosely-coupled' code relied much less on the environment around it. It would typically receive its values through an argument list, array of values it needs, or perhaps by being a method in a class which has attribute values for all of the necessary stuff. Other than that, it's not a huge issue. -- Torben Wilson <torben@php.net> +1.604.709.0506 http://www.thebuttlesschaps.com http://www.inflatableeye.com http://www.hybrid17.com http://www.themainonmain.com -----==== Boycott Starbucks! http://www.haidabuckscafe.com ====-----
