Re: event-based oop design

Threads would imply an application server, isn't it? For now I haven't met a PHP extension for such thing, only heard of. This would be a major turn for php, I think. I was referring to an user-instance-only event-based approach. Working on a big project, hundreads of objects, I wanted to know if an error popped up somewhere, or an event of given type happened.. For now error reporting is one-dimension push into a reporting channel. I was curious if anyone tried this. Tick is interesting! Calin ""Jesus M.
