A conditional wrapper for the stock env() command in Laravel. If the environment variable is not present, the default value returned is dependent upon the current application environment.

composer require erunion/env_cond

Say you have a config/services.php that looks like this:

<?php

return [
    'aws' => [
        's3_bucket' => env('AWS_S3_BUCKET', 'cdn.app.com')
    ]
];

With this, you'll need to store your development S3 bucket, dev.app in .env-dist so everyone on your team has that when they make their personal .env file. Now say that you need to change the default, you'll need to communicate with your entire team to change their default over to dev2.app.

With env_cond(), developers just need to worry about settings that they actually want to change.

<?php

return [
    'aws' => [
        's3_bucket' => env_cond('AWS_S3_BUCKET', 'dev.app', 'cdn.app.com')
    ]
];

Here, if a developer isn't working with a custom S3 bucket locally, they don't need to add AWS_S3_BUCKET="dev.app" into their .env file. If their environment is dev, or testing, their bucket will automatically be dev.app.

This makes your .env-dist and .env files a lot cleaner.
