​
Overview

You can reuse the same component for different contexts within a model. In this example, the TimeRange component is used for both $workTime and $leisureTime.

​
Example

<?php
$loader = require 'vendor/autoload.php';
$loader->add('Cognesy\\Instructor\\', __DIR__.'../../src/');

use Cognesy\Instructor\Instructor;

class TimeRange {
    /** The start time in hours. */
    public int $startTime;
    /** The end time in hours. */
    public int $endTime;
}

class UserDetail
{
    public string $name;
    /** Time range during which the user is working. */
    public TimeRange $workTime;
    /** Time range reserved for leisure activities. */
    public TimeRange $leisureTime;
}

$user = (new Instructor)->respond(
    messages: [['role' => 'user', 'content' => "Yesterday Jason worked from 9 for 5 hours. After that I watched 2 hour movie which I finished at 19."]],
    responseModel: UserDetail::class,
    model: 'gpt-4o',
);

dump($user);

assert($user->name == "Jason");
assert($user->workTime->startTime === 9);
assert($user->workTime->endTime === 14);
assert($user->leisureTime->startTime === 17);
assert($user->leisureTime->endTime === 19);
?>
