This is a simple but useful PHP Class that you can use to communicate with Anthropic's Claude via API.

composer require dikki/claude-sdk

First, create an instance of the Claude class. Pass the API key as the first parameter. You can pass the model name as the second parameter or keep it empty to use the default model (claude-2.1).

$claude = new \Dikki\Claude\Claude($apiKey, 'claude-2.1');

To get the whole response from Claude, use the getResponse() method. It accepts the following parameters:

• string $prompt: The prompt to send to the API.
• array $messages: Optional. The messages to send to the API.
• string|null $model: Optional. The model to use for the API request.
• int $maxTokens: Optional. The maximum number of tokens to generate (default is 4000).
• string $method: Optional. The HTTP method to use for the request (default is 'POST').

Returns an array containing the full response, including text, model used, etc.

$response = $claude->getResponse("Write an essay on AI.");

To get only the string response, use the getTextResponse() method. It accepts the same parameters as getResponse().

Returns a string response.

$response = $claude->getTextResponse("Write an essay on AI.");

// Create an instance of Claude
$claude = new \Dikki\Claude\Claude($apiKey, 'claude-2.1');

// Get full response
$response = $claude->getResponse("Write an essay on AI.");

// Get only text response
$textResponse = $claude->getTextResponse("Write an essay on AI.");
