On the Internet Super Hero blog there's a recent post talking about a PHP event happening June 15th through the 21st visiting several German user groups (including ones in Frankfurt, Karlsruhe and Berlin) - the PHP BBQ Tour.

It is getting summer in Germany: let's have a PHP BBQ tour! The PHP BBQ tour is one week tour from Monday, 15.06. - Sunday, 21.06.2009 visiting the german PHP user groups. The tour will go through Munich, Frankfurt, Karlsruhe, Berlin, Dortmund, Hamburg and Kiel. The tour is an offering and a suggestion to the user group to come together for a barbecue instead of meeting in conference rooms in the middle of the summer, when the days are long. Everybody is invited to join me and other MySQLers on the tour to visit the PHP user group in his neighbor town.

Check the blog post for when they'll be in which cities and what will be happening while they're there. They've also set up a wiki page for more information.
