phpdotenv | Loads environment variables from .env to getenv | Continous Integration library

Normally, you have a bootstrap file where you include both Composer's autoload.php and other common stuff, e.g. the instantiation of Dotenv. This can be an index.php file which handles all incoming requests (the most common pattern you will find in frameworks, Laravel does the same: https://github.com/laravel/laravel/blob/8e5510458e1a4c0bf4b78024d9b0cf56102c8207/public/index.php#L34) or some other file you will include in all your .php files that are handling requests (if you are not using a common index.php).

If you want to learn more about how frameworks work, I suggest you browse & read their code. You can start with something smaller (like Slim).

LATER EDIT - DUMMY TUTORIAL:

Alright, let's build a very basic project:

Step 1. We start with the following:

composer.json

Maybe it's because of caching the config. It is better to load your env variable in a config file and then retrieve it from the config. For example you can create a file with the name 'ips' in config directory like this:

You need to specify backslash before AcceptanceTester class name in the methods signatures to find class in the root namespace:

public function signUp(\AcceptanceTester $I)

public static function fillGetQuickAndEasyPrice(\AcceptanceTester $I, $address, $name, $phone)

PHP 7+ Closure has some interesting features, which can bypass private/protected checks. It is very hacky, however, pretty good for test cases written.

Travis CI keeps a cache of your vendor folder in order to make builds run quicker (and reduce unnecessary traffic for them). If you've made some changes to your composer.lock file Travis CI may need to update the files stored in the vendor folder.

Other times it won't need to do this, and so will have a shorter build time.

This seems to be a problem with the virtual box filesystem. I created an issue to composer and hopefully more insight will be gained.

So let's look at this. Your directory structure seems to be something like this:

All packages that are being installed using composer are kept under directory named as vendor. So you will see all installed packages over here.

Now there is a feature that you require in your project(Loading environment variables from .env) and for that you're using another package(vlucas/phpdotenv) as your project dependency.

In the same manner vlucas/phpdotenv package is also developed by another developer who relies on multiple packages for his project to work smoothly just like yours. So all packages which were used in this package as dependency will also be installed in your vendor folder.

Now how these are installed: Check composer.json file at root of your project. It contains keys like require and require-dev, data inside these attributes tells composer to install packages for your project.

In the same way when you'll look composer.json of vlucas/phpdotenv project, you'll see a list of all of your mentioned packages inside that. Composer auto detects them and install them, so you don't have to manually installed them to make vlucas work in your project.

composer.json file of vlucas/phpdotenv.

I used this and It works for me.
