The Dutch PHP Conference has officially opened their Call for Papers for this year's event (happening in early June):

We're back! And we are glad to announce that we'll be organising another edition of the Dutch PHP Conference, which will be held in Amsterdam from 6th to 8th June 2013.

Submissions should be relevant to PHP developers, to help them to expand their skill set and improve their practices. In particular we'd like to receive proposals regarding emerging technologies, performance and scalability, platforms and best practices. The standard conference sessions should be 45 minutes and tutorials are 3 or 6 hours in length (note that 6 hours is our preference).

As always we're excited about all kinds of different topics. You could say that as long as it's somehow related to PHP and you're really excited about it, we want to hear it!

You can find out more about the conference in general from the main conference site.
