README
Caridea is a miniscule PHP application library. This shrimpy fellow is what you'd use when you just want some helping hands and not a full-blown framework.
This is its HTTP component. It includes small utilities for working with PSR-7 HTTP requests and responses, including:
- An implementation of RFC 7807, "Problem Details for HTTP APIs".
- A utility to parse common pagination parameters from the request
- A utility to correctly parse query strings with multiple parameters having the same name
- A utility to determine a client's preferred accepted MIME type

Examples
Just a few quick examples.
Problem Details
We included an implementation of RFC 7807 that you can serialize to JSON or append to a PSR-7 HTTP Response.
use Caridea\Http\ProblemDetails; use Zend\Diactoros\Uri; $problem = new ProblemDetails( new Uri('http://example.com/problem/oops'), // type 'A weird thing happened', // title 500, // status 'It looks like the server has goofed again', // detail new Uri('http://example.com/problems/1f9a'), // instance [ // extensions 'server' => 'workerbee01.example.com', 'auth' => 'foobar' ] ); echo json_encode($problem);
Pagination Factory
use Zend\Diactoros\ServerRequestFactory; $request = ServerRequestFactory::fromGlobals( $_SERVER, \Caridea\Http\QueryParams::getFromServer(), // instead of $_GET ); $factory = new \Caridea\Http\PaginationFactory(); // say the Query was ?count=25&startIndex=1&sort=%2Bfoo&sort-bar // or maybe ?count=25&start=0&sort=%2Bfoo,-bar // or one of many other formats for this type of pagination settingns $pagination = $factory->create($request, 'sort'); $pagination->getMax(); // 25 $pagination->getOffset(); // 0 $pagination->getOrder(); // ['foo' => true, 'bar' => false]
Accept Types
// say the HTTP_ACCEPT field is text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 $types = new \Caridea\Http\AcceptTypes($_SERVER); $types->preferred(['application/xml', 'application/json']); // returns application/xml
Helper Traits
Two traits are now available, JsonHelper
and MessageHelper
. These can be used by controller classes or dispatcher middleware.
Third-Party
The traits JsonHelper
and MessageHelper
(as well as their unit tests) were ported to PHP from the Labrys library under a compatible Apache 2.0 license.
