If you're working with PHP, the official Infisical PHP SDK package is the easiest way to fetch and work with secrets for your application.

## Installation

```bash
composer require infisical/php-sdk
```

## Getting Started

```php
<?php

use Infisical\SDK\InfisicalSDK;

$sdk = new InfisicalSDK('https://app.infisical.com');

// Authenticate with Infisical
$response = $sdk->auth()->universalAuth()->login(
    "your-machine-identity-client-id",
    "your-machine-identity-client-secret"
);

// List secrets
$params = new \Infisical\SDK\Models\ListSecretsParameters(
    environment: "dev",
    secretPath: "/",
    projectId: "your-project-id"
);

$secrets = $sdk->secrets()->list($params);
echo "Fetched secrets: " . count($secrets) . "\n";
```

## Core Methods

The SDK methods are organized into the following high-level categories:

1. `auth`: Handles authentication methods.
2. `secrets`: Manages CRUD operations for secrets.

### `Auth`

The `auth` component provides methods for authentication:

#### Universal Auth

**Authenticating**
```php
$response = $sdk->auth()->universal_auth()->login(
    "your-machine-identity-client-id",
    "your-machine-identity-client-secret"
);
```

**Parameters:**
- `clientId` (string): The client ID of your Machine Identity.
- `clientSecret` (string): The client secret of your Machine Identity.

<Warning>
  We do not recommend hardcoding your [Machine Identity Tokens](/documentation/platform/identities/overview). Setting them as environment variables would be best.
</Warning>

### `Secrets`

This sub-class handles operations related to secrets:

#### List Secrets

```php
use Infisical\SDK\Models\ListSecretsParameters;

$params = new ListSecretsParameters(
    environment: "dev",
    secretPath: "/",
    projectId: "your-project-id",
    tagSlugs: ["tag1", "tag2"], // Optional
    recursive: true, // Optional
    expandSecretReferences: true, // Optional
    attachToProcessEnv: false, // Optional
    skipUniqueValidation: false // Optional
);

$secrets = $sdk->secrets()->list($params);
```

**Parameters:**
- `environment` (string): The environment in which to list secrets (e.g., "dev").
- `projectId` (string): The ID of your project.
