$message = $client->messages->create(
|
|
model: 'claude-opus-4-6',
|

maxTokens: 1024,
|
|
messages: [
|

['role' => 'user', 'content' => 'What is the capital of France?'],

maxTokens: 1024,
|
|
messages: [

|
['role' => 'user', 'content' => 'Write a haiku'],

## Tool Use (Manual Loop)
|
|
|
|
The PHP SDK supports raw tool definitions via JSON schema. See the [shared tool use concepts](../shared/tool-use-concepts.md) for the tool definition format and agentic loop pattern.
