Calculate Lines of Code

https://stackoverflow.com/questions/1358540/how-to-count-all-the-lines-of-code-in-a-directory-recursively

You also have this package https://github.com/stefanzweifel/laravel-stats that you can use to see lines of code (groupped by models, controllers, etc...) like using rake stats in rails

I also use phploc for this kind of thing.
