> Part of **[Jardis](https://jardis.io)** — the Domain-Driven Design platform for PHP. You model your domain; Jardis generates the production-ready hexagonal code (DTOs, Command/Query handlers, repositories, persistence). This package is part of the open-source foundation that generated code runs on.

A .env loader for PHP with cascading overrides, variable interpolation, type casting, and include directives. Goes beyond simple .env parsing — supports public and private loading modes, nested variable references, and an extensible cast chain.

---

Features
--------

[](#features)

- **Public/Private Loading** — `loadPublic()` writes to `$_ENV`/`$_SERVER`; `loadPrivate()` returns an isolated array without touching global state
- **Cascading Overrides** — two-stage loading: base `.env` first, then `APP_ENV`-specific files (e.g. `.env.production`) override selectively
- **Variable Interpolation** — `${VAR}` references are resolved against already-loaded values in the same file
- **Type Casting Chain** — automatically converts strings to `bool`, numeric, JSON, and `array` via a chainable handler pipeline
- **Home Path Expansion** — `~/` is expanded to the OS home directory in both loading modes
- **Include Directives** — `load(.env.database)` and `load?(.env.optional)` split configuration across multiple files
- **Circular Include Detection** — prevents infinite include loops with a typed `CircularEnvIncludeException`
- **Docker `_FILE` Secret Resolution** — `DB_PASSWORD_FILE=/run/secrets/db_password` reads the file and exposes the content as `DB_PASSWORD`. Works with Docker Swarm, Kubernetes mounted secrets, and any file-based secret store. Combines with [`jardissupport/secret`](https://github.com/jardisSupport/secret) — a `_FILE` that contains `secret(aes:...)` is decrypted automatically through the cast chain
- **Extensible via `addHandler()`** — prepend or append custom cast handlers; remove built-in ones via `removeHandler()`

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

[](#installation)

```
composer require jardissupport/dotenv
```

Quick Start
-----------

[](#quick-start)

```
use JardisSupport\DotEnv\DotEnv;

$dotEnv = new DotEnv();

// Write into $_ENV / $_SERVER / putenv — suitable for application bootstrap
$dotEnv->loadPublic('/path/to/app');

// Return an isolated array — no global state, suitable for bounded contexts
$config = $dotEnv->loadPrivate('/path/to/domain');

echo $config['DB_HOST']; // 'localhost'
echo $config['DEBUG'];   // bool(true) — automatically cast
```

Advanced Usage
--------------

[](#advanced-usage)

```
use JardisSupport\DotEnv\DotEnv;
use JardisSupport\DotEnv\Handler\CastStringToBool;
use JardisSupport\Secret\Handler\SecretHandler;
use JardisSupport\Secret\KeyProvider\FileKeyProvider;

// .env example:
//
//   APP_ENV=production
//   load(.env.database)           loadPrivate('/path/to/app');
```

### Docker Secret Files (`_FILE` Pattern)

[](#docker-secret-files-_file-pattern)

Read secrets from mounted files — the industry-standard pattern for Docker Swarm and Kubernetes:

```
# .env
APP_NAME=MyApp
DB_HOST=localhost
DB_PASSWORD_FILE=/run/secrets/db_password
REDIS_TOKEN_FILE=/run/secrets/redis_token
```

```
$config = (new DotEnv())->loadPrivate('/path/to/app');

echo $config['DB_PASSWORD'];  // content of /run/secrets/db_password
echo $config['REDIS_TOKEN'];  // content of /run/secrets/redis_token
// DB_PASSWORD_FILE / REDIS_TOKEN_FILE are NOT in the result
```

The `_FILE` suffix is stripped, the file content is read and passed through the full cast chain — variable substitution, type casting, and even secret decryption all work:

```
# _FILE + secret() combined: file contains encrypted value
# /run/secrets/db_password contains: secret(aes:base64encodedValue)
DB_PASSWORD_FILE=/run/secrets/db_password
```

```
$dotEnv = new DotEnv();
$dotEnv->addHandler(
    new SecretHandler(new FileKeyProvider('support/secret.key')),
    prepend: true,
);
$config = $dotEnv->loadPrivate('/path/to/app');
// DB_PASSWORD → file read → secret() decrypted → plaintext
```
