Find the model a setting is for?

[designvoid]

I am building some logging and am recording models being saved - when a setting is saved I want to save the id of the model the setting was for - I only have access to the setting model instance - is there a way to pull it from the context in the key? Not sure how to best deconstruct that?

[designvoid]

I have got it working like this but wondering if there's a nicer way I'm missing?

<?php

declare(strict_types=1);

namespace App\Services;

use InvalidArgumentException;
use Rawilk\Settings\Support\Context;

class SettingsService
{
    public function decodeContextString(string $serializedString): array
    {
        $serializedPart = substr($serializedString, strpos($serializedString, 'O:31:'));

        $object = unserialize($serializedPart, ['allowed_classes' => true]);

        if ($object instanceof Context) {
            return $object->toArray();
        }

        throw new InvalidArgumentException('Failed to unserialize the object.');
    }
}
