Overview

When you need to extract undefined attributes, use a list of key-value pairs.

​
Example

<?php

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

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



use Cognesy\Instructor\Enums\Mode;

use Cognesy\Instructor\Instructor;



class Property

{

    public string $key;

    public string $value;

}



class UserDetail

{

    public int $age;

    public string $name;

    /** @var Property[] Extract any other properties that might be relevant */

    public array $properties;

}

?>

Now we can use this data model to extract arbitrary properties from a text message in a form that is easier for future processing.

<?php

$text = <<<TEXT

    Jason is 25 years old. He is a programmer. He has a car. He lives

    in a small house in Alamo. He likes to play guitar.

    TEXT;



$user = (new Instructor)->respond(

    messages: [['role' => 'user', 'content' => $text]],

    responseModel: UserDetail::class,

    mode: Mode::Json,

);



dump($user);



assert($user->age === 25);

assert($user->name === "Jason");

assert(!empty($user->properties));

?>
