Best Conference Ever!

I would like to attend *one* conference next year. Based on your past experiences, what would think is the most rewarding experiences?

My role is largely as a PHP builder with a role in an upcoming site redesign that will put a CMS in place.

If you are a PHP coder, then why don't you attend a php specific conference?

This is the list of currents for two reasons:
- I can't find a list of 2006 PHP-specific events. Does anyone know of one or more 2006 PHP-specific events?
- What I code in PHP will have a real world application: these three talk about the big picture of web development and Internet technology.

If you are looking for "big picture" kinda conference - Zend is giving one this year in San Fran. It deals with PHP at the enterprise level. They have major companies coming out to discuss the "Business" side and yet they also have a developer "Technical" side.

Is this for 2006 - nope 2005. But I would be greatly surprised if they don't hold one again next year.
