I want to see code for other programmers to learn from it, for instance: I learnt about PHP, OOP & MVC , but I want to blend all together practically (Like a login system app) , so I really want to see other people code, How Can I do It?
I have found Code Review, on the Stack Exchange network, useful for this sort of thing. Here's the current code reviews for PHP
If you are already into PHP, OOP and MVC you can pay $9 a month and watch the courses on laracasts.com. Jeffrey Way is an amazing coder and teacher and I've learn a lot just by watching him code and coding along with his courses. You can even watch his free course on PHP basics
