Informations about the package php-exceptions
php-exceptions
A curated set of reusable, semantic domain exceptions for Domain-Driven Design PHP applications. Their names mirror the HTTP 4XX/5XX families because that vocabulary is widely understood, but they are raised in the domain layer, outside any transport, and translated at the boundary into an HTTP response, RPC error, CLI exit or queue dead-letter. Throwing the right exception is part of your domain language, where a generic InvalidArgumentException leaks plumbing into it. Framework-agnostic, with zero runtime dependencies beyond the PHP standard library, on any PHP 8.1+ project.
- Client exceptions - caller-fault types aligned to the 4XX family, from
BadRequestExceptionthroughUnavailableForLegalReasonsException, each with a default message and status code. - Server exceptions - system-fault types aligned to the 5XX family, from
InternalServerErrorExceptionthroughLoopDetectedException. AbstractBaseException- the common base, extending PHP's native\DomainException, so a singlecatchcaptures everything in this package.Request\RequestFailureException- structured per-field validation failures, for one rejected payload carrying many reasons.- Extension by intent - every type is meant to be extended by your own named exception, so callers can still catch the broader intent.

Installation
Usage
Every exception in this package extends AbstractBaseException, which itself extends PHP's native \DomainException. Each subclass ships with a sensible default message and an HTTP-aligned status code ($code).
Catching by intent
Authoring your own exceptions
Pick the closest leaf class and extend it — that way callers can still catch by the broader intent.
Available exceptions
Listed in HTTP-status order for orientation. Each class carries a docBlock with its semantic meaning, when to extend it, and (where relevant) the browser behaviour the analogous HTTP status triggers.
Client — caller-fault (4XX-aligned)
BadRequestException (400), DeniedAccessException (401), PaymentRequiredException (402), ForbiddenException (403), NotFoundException (404), MethodNotAllowedException (405), NotAcceptableException (406), RequestTimeoutException (408), ConflictException (409), GoneException (410), PreconditionFailedException (412), UnsupportedMediaTypeException (415), RequestedRangeNotSatisfiableException (416), ExpectationFailedException (417), UnprocessableEntityException (422), LockedException (423), FailedDependencyException (424), TooEarlyException (425), PreconditionRequiredException (428), TooManyRequestsException (429), UnavailableForLegalReasonsException (451), plus Request\RequestFailureException for structured per-field validation failures.
Server — system-fault (5XX-aligned)
InternalServerErrorException (500), ServerNotImplementedException (501), BadGatewayException (502), ServerUnavailableException (503), GatewayTimeoutException (504), InsufficientStorageException (507), LoopDetectedException (508).
Transport-only HTTP statuses (407, 411, 413, 414, 421, 426, 431, 505, 506, 510, 511) are intentionally not represented — they have no platform-agnostic domain meaning.
