// 使用环境变量中的 API key
$client = new Client(apiKey: getenv("ANTHROPIC_API_KEY"));

    maxTokens: 1024,
    messages: [
        ['role' => 'user', 'content' => 'What is the capital of France?'],
    ],
);
echo $message->content[0]->text;

$stream = $client->messages->createStream(
    model: '{\{OPUS_ID}\}',
    maxTokens: 1024,
    messages: [
        ['role' => 'user', 'content' => 'Write a haiku'],
    ],
);

foreach ($stream as $event) {
