Accessing ENV vars from PHP

# 1. use the getenv function
echo getenv("MY_ENV_VAR");

# 2. use the global
echo $_SERVER["MY_ENV_VAR"];
php

1. The getenv() PHP function accepts a key and returns it's value.
2. Use the global variable $_SERVER.

Frameworks and content management systems will parse and use ENV vars automatically. Usually .env files are supported for local development. A config file to grab may $dbHost = env('DB_HOST');.

• Laravel: Use the env() helper function
