Re: Statics and PHP5

Jonathan, Thanks for the reply. Actually, my question was not a "how to use", but definitely a "what are you doing?" intended for the PHP authors (i.e. the Zend folks). Logging is a great example of what I'd like to do, but won't work in the current PHP5 implementation. If you write a Logger class as a singleton, and a page makes 10 calls to the logger, then sure, those 10 calls will use the same instance of Logger. But if there are say 10 pages in a users' progression, then you'd get 10 singletons created just for that user (thereby not actually being a singleton at all). And if there were 100 concurrent users, there would be 100*10 instances of Logger created, 100 at the same time--definitely not a singleton. No other languages behave this way (not Java or C# for sure). Thanks for the pointer to that other framework.
