I never really left Bla. You can still message me if you want any help or what have you. Anyway, so you want to learn more about php. In that case, I'm gonna throw some links at you:
https://phpacademy.org/ - they have php tutorial videos, should be helpful
http://thenewboston.org/tutorials.php - more videos, cause why not, they also have other programming language tutorials besides php
http://net.tutsplus.com/articles/web-roundups/25-resources-to-get-you-started-with-php-from-scratch/ - a resource link though idk how many of the links work, it should be useful
Might as well throw some more programming links at you:
http://www.codecademy.com/ - interactive website that helps you learn a few programming languages, it has exercises and all that jazz
Never used these next two but they provide actual college courses that you can enroll in for free online:
http://www.udacity.com/
https://www.coursera.org/
I think those resources are a good starting point.
