The Call-for-Papers for the International PHP Conference 2006, 5-8 November in Frankfurt (Germany) has been extended. So, there’s still some more time to get your ideas in there!
The PHP conf is organisationally interesting (perhaps only to those of us who are involved in organising conferences 😉 because it has fairly long regular sessions (75 minutes), speakers can go into considerable depth. There are also “power workshops” which are 3 or 6 hours long.
It’s also a place were core PHP developers and others meet. There are many conferences, but some are considerably more interesting than others… I’ve been to this one for the few years or so, and it’s been excellent.
