CTW HTTP

This repository holds utility classes and constants to facilitate common operations of PSR-7 and a group of exceptions which represent HTTP status codes.

Installation

Install by adding the package as a Composer requirement:

$ composer require ctw/ctw-http

Usage Examples

Returning an Entity

use Ctw\Http\HttpStatus;

$httpStatus = new HttpStatus(HttpStatus::STATUS_NOT_FOUND);
dump($httpStatus->get());

^ Ctw\Http\Entity\HttpStatus^ {#2
  +statusCode: 404
  +name: "Not Found"
  +phrase: "The requested resource could not be found but may be available again in the future."
  +exception: "Ctw\Http\HttpException\NotFoundException"
  +url: "https://httpstatuses.com/404"
}

Throwing Exceptions

HttpException\* Exceptions

use Ctw\Http\HttpException;

throw new HttpException\NotFoundException();

PHP Fatal error: Uncaught Ctw\Http\HttpException\NotFoundException: 
  404 Not Found in /path/demo-usage.php:20
Stack trace:
#0 {main}
  thrown in /path/demo-usage.php on line 20

HttpException\* Exception with Custom Error Message

use Ctw\Http\HttpException;

throw new HttpException\NotFoundException('Custom 404 error message');

PHP Fatal error: Uncaught Ctw\Http\HttpException\NotFoundException: 
  Custom 404 error message in /path/demo-usage.php:21
Stack trace:
#0 {main}
  thrown in /path/demo-usage.php on line 21

Catching Exceptions

All HttpException\* Exceptions implement HttpException\HttpExceptionInterface, therefore:

use Ctw\Http\HttpException;

try {
    throw new HttpException\NotFoundException();
} catch (HttpException\HttpExceptionInterface $e) {
    dump($e->getStatusCode());
    dump($e->getMessage());
}

The HttpException\* hierarchy is:

use Ctw\Http\HttpException\HttpExceptionInterface;
use Ctw\Http\HttpException\AbstractException;
use Ctw\Http\HttpException\AbstractClientErrorException;
use Ctw\Http\HttpException\AbstractServerErrorException;

HttpExceptionInterface
└── AbstractException
    ├── AbstractClientErrorException
    │   └── *Exception
    └── AbstractServerErrorException
        └── *Exception
