Simple environment variables loader library for PHP. It loads environment variables from a .env file. It requires PHP 7.2+ and is compliant with [PSR-1](http://www.php-fig.org/psr/psr-1/ "PSR-1: Basic Coding Standard"), [PSR-4](http://www.php-fig.org/psr/psr-4/ "PSR-4: Autoloader"), [PSR-12](http://www.php-fig.org/psr/psr-2/ "PSR-12: Extended Coding Style Guide").

Installation
------------

[](#installation)

Install via the `composer` utility.

```
composer require "phoole/env"

```

or add the following lines to your `composer.json`

```
{
    "require": {
       "phoole/env": "1.*"
    }
}
```

Usage
-----

[](#usage)

- Put your environments in file `.env`. By default, existing environment variables are **not overwritten**.

    ```
    # this is comment line
    BASE_DIR = /usr/local  # spaces allowed

    # use reference here
    APP_DIR = ${BASE_DIR}/app   # /usr/local/app

    # use bash style :- or :=
    TMP_DIR = ${SYSTEM_TMP_DIR:-${APP_DIR}/tmp}
    ```

    See [shell variable expansion](https://www.gnu.org/software/bash/manual/html_node/Shell-Parameter-Expansion.html "Shell Variable Expansion") for `:-` and `:=` usage.
- Load and use your env variables in PHP script

    ```
