​
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);
