[](#installation)

```
composer require env-interop/impl

Usage

[](#usage)

Load a base environment file, with an optional local override:

```
use EnvInterop\Impl\EnvLoader;

new EnvLoader()
    ->loadEnv('.env.ini')
    ->loadEnvIfReadable('.env.local.ini');
```

Read values from the environment:

```
use EnvInterop\Impl\Env;

$env = new Env();

$pdo = new PDO(
    $env->getEnv('PDO_DSN'),
    $env->getEnv('PDO_USERNAME'),
    $env->getEnv('PDO_PASSWORD'),
);
```

Add or replace environment variables:

```
use EnvInterop\Impl\EnvSetter;

$setter = new EnvSetter();
$setter->addEnv('FEATURE_FLAG', true);   // only if not already set
$setter->setEnv('DEBUG', false);         // always replaces; null unsets
```

Parse environment contents directly (INI syntax, via `parse_ini_string()`):

```
use EnvInterop\Impl\EnvParser;

$parsed = (new EnvParser())->parseEnv(
