Api Problem
This package provides a RFC7807 Problem details implementation. It can be integrated everywhere in your code and should result in a general error response format for HTTP APis.
This package only provides a generic interface, an exception class and some built-in api problem messages. Since handling the exceptions is up to the framework, here is a list of known framework integrations:
- Symfony
^4.1: ApiProblemBundle
Installation
composer require phpro/api-problem
Usage
This package provides a general interface for creating ApiProblem value objects.
use Phpro\ApiProblem\Exception;
throw new ApiProblemException(
new HttpApiProblem(418, ['detail' => 'Did you know 4,000 people are injured by teapots every year?!'])
);

Creating your own problem
Creating problem sounds scary right!? Since the RFC is very loose, we made the interface as easy as possible:
use Phpro\ApiProblem\ApiProblemInterface;
class MyProblem implements ApiProblemInterface
{
public function toArray(): array
{
return [
'type' => 'about:blank',
'status' => '99',
'title' => 'Got 99 problems but a glitch aint one!',
];
}
}
A lot of problems will be detected in an HTTP context. Therefore, we also provided a base HttpApiProblem class.
This one will automatically fill in the type and title section based on the HTTP code.
The only thing you'll need to do, is add some additional data to it:
use Phpro\ApiProblem\Http\HttpApiProblem;
class MyProblem extends HttpApiProblem
{
public function __construct(string $details)
{
parent::__construct(500, ['details' => $details]);
}
}
If you want to log additional information in a debug context, it is possible to implement an additional DebuggableApiProblemInterface:
use Phpro\ApiProblem\DebuggableApiProblemInterface;
class MyProblem implements DebuggableApiProblemInterface
{
public function toArray(): array
{
return [
'type' => 'about:blank',
'status' => '99',
'title' => 'Got 99 problems but a glitch ain\'t one!',
];
}
public function toDebuggableArray(): array
{
return array_merge(
$this->toArray(),
[
'situation' => 'If you are having code problems, I feel bad for you son',
]
);
}
}
