Anthropic PHP
=============

[](#anthropic-php)

Anthropic PHP is library to interact with Anthropic API, this library is designed to be close to OpenAI PHP. The goal of this library is to have the same API to OpenAI PHP client, so you can switch from GPT model to Claude easily.

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

[](#installation)

Make sure you are using php: ^8.1.0.

```
composer require ahmadrosid/anthropic-php
```

How to use?
-----------

[](#how-to-use)

Create anthropic client.

```
use Anthropic\Anthropic;

$client = Anthropic::factory()
    ->withHeaders([
        'anthropic-version' => '2023-06-01',  // Required!
        'content-type' => 'application/json',
        'x-api-key' => env('ANTHROPIC_API_KEY', '')
    ])
    ->make();
```

**Important:** The `anthropic-version` header is required. Without it, you'll get a 404 error.

[](#using-model-constants)

You can use the `Model` class for convenient access to model identifiers:

```
use Anthropic\Model;

$response = $client->chat()->create([
    'model' => Model::CLAUDE_OPUS_4_7,
    'max_tokens' => 4096,
    'messages' => [
        ['role' => 'user', 'content' => 'Hello!']
    ]
]);
```

Chat with Claude
----------------

[](#chat-with-claude)

Send chat message.

```
$response = $client->chat()->create([
    'model' => 'claude-opus-4-7',
    'max_tokens' => 4096,
    'system' => 'You are a helpful assistant.',
    'messages' => [
        [
            'role' => 'user',
            'content' => 'Hello, how are you?'
        ]
    ]
]);

$content = $response->choices[0]->message->content;
echo $content;
```

Chat Streaming
--------------

[](#chat-streaming)

Process server sent event reply from chatbot.

```
$model = 'claude-sonnet-4-6';
$max_tokens = 4096;
$temperature = 0;
$systemMessage = 'Always reply with "Hello!"';
$messages = [
    [
        'role' => 'user',
        'content' => 'Hi there...'
    ]
];
$stream = $client->chat()->createStreamed([
    'model' => $model,
    'temperature' => $temperature,
    'max_tokens' => $max_tokens,
    'system' => $systemMessage,
    'messages' => $messages,
]);

foreach ($stream as $response) {
    $text = $response->choices[0]->delta->content;

    echo $text;
}
```

Testing
-------

[](#testing)

This package includes both unit tests and integration tests.

### Running Unit Tests

[](#running-unit-tests)

Unit tests use mocked HTTP clients and don't require an API key:

```
composer test
```

Or run only unit tests:

```
vendor/bin/phpunit --testsuite Unit
```

### Running Integration Tests

[](#running-integration-tests)

Integration tests make real API calls to Anthropic. To run them:

1. Copy `.env.example` to `.env`:

    ```
    cp .env.example .env
    ```
2. Add your Anthropic API key to `.env`:

    ```
    ANTHROPIC_API_KEY=your-api-key-here

    ```
3. Run integration tests:

    ```
    vendor/bin/phpunit --testsuite Integration
    ```

**Note:** Integration tests will consume API credits.
