Microservices comes for free with PHP. No need to have some specific support. I've answered a similar question elsewhere. But basically, I don't like the current trend of making everything more difficult than it should be. Adding layers of abstractions makes your infrastructure exponentially more complex. Think twice before adding a new layer. I'm not saying it's not needed... sometimes. But for the vast majority of the projects out there, keep it simple :)

It is more than ok to learn more than 1 framework. We should be developers, not PHP developers, or Wordpress developers. A developer should always try to learn new things. When I hire someone, I like curious people, with interesting and unusual backgrounds. If you know more than one framework and more than one language, you will adapt more easily. Learning a new language or a new framework is much easier when you know other ones. Adaptability is the key here I suppose.

I've answered the questions about hate in another question. Regarding the creation of a startup, are you talking about a startup selling products for PHP developers?

We are at the very beginning of the Diversity initiative. Lukas is doing an amazing job, but we are still iterating on the best possible processes. Transparent processes is an important goal for us. I like that we now have a dedicated team working on such an important topic. There are so many things to do and still a lot to accomplish. My role as the creator of Symfony is to ensure that everyone is welcome in the community. I don't want us to rest on our laurels just because we started to make some small (significant) changes. Symfony is a community. And after so many years, code is becoming less important. Community is first. And diversity is probably the most important part of any community. It's challenging, but I like challenges!

Developing a framework like Symfony is a lot of work. We do have many admin gen written by the community and that's the great thing about Symfony. I don't have to do it all :)

I don't know how to answer this one as I don't have an average day! They are all different. Sometimes, I don't feel like coding, so I don't code for days/weeks. And then, when I feel motivated to fix an issue, I can code for hours. But I'm always trying to find the right balance between work and family time.

I think Symfony 4 changes the game here. I've moved many projects from Silex to Symfony 4 and the code was more explicit and easier to read after the move. So, to me, Silex is not needed anymore.

A framework is the low-level foundation for projects. And people don't pay for low-level and technical libraries. Linux is free. So, almost all frameworks are free. So, having a paid version of Symfony would not work IMHO. But to be honest, being a billionaire has never been one of my goals; as an entrepreneur, I make some good money and that's enough for me.

As I answered elsewhere, I've never used PHP exclusively. Nowadays, I'm doing a lot of Go. Go is very complementary to PHP. Everything I would do with PHP is not a good fit for Go. And the other way around. Having PHP, Go, and JavaScript is probably enough for most of my projects.

I'm not sure developers take the quick and easy way when working on a project. They choose the right tool for the job, depending on their constraints. I'm not always using Symfony for my projects. Wordpress is great when doing a blog. Go is great when developing an HTTP daemon. Symfony is great when developing a project where many developers should work together for a long-term success.
