Re: [PHP-PEAR] 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!
