​
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.

We’re additionally starting the data structure with a Chain of Thought field to elicit LLM reasoning for the time range calculation, which can improve the accuracy of the response.

​
Example

<?php

$loader = require 'vendor/autoload.php';

$loader->add('Cognesy\\Instructor\\', __DIR__.'../../src/');



use Cognesy\Instructor\Instructor;



class TimeRange

{

    /** Step by step reasoning to get the correct time range */

    public string $chainOfThought;

    /** The start time in hours (0-23 format) */

    public int $startTime;

    /** The end time in hours (0-23 format) */

    public int $endTime;

}



$timeRange = (new Instructor)->respond(

    messages: [['role' => 'user', 'content' => "Workshop with Apex Industries started 9 and it took us 6 hours to complete."]],

    responseModel: TimeRange::class,

    maxRetries: 2

);



dump($timeRange);



assert($timeRange->startTime === 9);

assert($timeRange->endTime === 15);
