hi, I never used Phalcon before. Where can I find more documents or video for tutorial? or samples?
You can read the documentation and read examples about building a complete application, like INVO : http://docs.phalcon.io/en/latest/reference/tutorial-invo.html
The code is available here : https://github.com/phalcon/invo
(There are others similar demo apps)
also you can find a video course on udemy (paied) made by @JREAM,
ore a book ( Author @Stephan Miller )-> http://www.packtpub.com/getting-started-with-phalcon/book
on the net, there is not much to find yet. So, as @Corentin wrote, I would recomment to read the docs and have a look at the sample apps.
any other documents from outside of the phalcon web site?
as I said, there is not much yet, here is an example using phalcon and angularjs. But it's a bit outdated:
i'll make a tut's list when i'll have time.
