General usage

Implementing friendly exception

To make exception friendly require this package and implement FriendlyExceptionInterface:

<?php

declare(strict_types=1);

use Yiisoft\FriendlyException\FriendlyExceptionInterface;

class RequestTimeoutException extends \RuntimeException implements FriendlyExceptionInterface
{
    public function getName(): string
    {
        return 'Request timed out.';
    }
    
    public function getSolution(): ?string
    {
        return <<<'SOLUTION'
            Likely it is a result of resource request is not responding in a timely fashion. Try increasing timeout.
            SOLUTION;
    }
}

When returning solution consider the following best practices:

1. Make solution description as short as possible.
2. Do not use HTML tags.
3. A simple markdown is OK but its support is up to implementation.

Handling friendly exception

To make your exception handler render friendly exceptions:

use Yiisoft\FriendlyException\FriendlyExceptionInterface;

class ThrowableHandler
{
    public function handle(\Throwable $t)
    {
        if ($t instanceof FriendlyExceptionInterface) {
            // additional handling
        }
        // regular handling
    }
}
