README

HTTP layer for PivotPHP: a thin Express.js-style facade on top of PSR-7 messages. The underlying representation is nyholm/psr7; PivotPHP adds the ergonomic API that a framework inspired by Express.js needs.

This package is pure HTTP: it depends only on nyholm/psr7, nyholm/psr7-server and the PSR interfaces — no dependency on the PivotPHP kernel, container or router.

Why a facade?

PSR-7 is excellent at representing HTTP messages but deliberately minimal — it has no param() or json() helpers. PivotPHP keeps its Express.js syntax by wrapping the PSR-7 objects:

$app->get('/api/users/:id', function ($req, $res) {
    return $res->json([
        'id'   => $req->param('id'),
        'name' => 'John Doe',
    ]);
});

Features

• ExpressRequest — read facade over ServerRequestInterface.
• ExpressResponse — fluent facade over ResponseInterface.
• BodyParser / Middleware\BodyParsingMiddleware — parse JSON and form bodies (including PUT/PATCH/DELETE).
• Emitter\SapiEmitter — emit the response to the SAPI (status/headers once, streamed body, no body on HEAD).
• Factory\Psr17Factory / Factory\ServerRequestFactory — PSR-17 and fromGlobals()/fromArrays().
• Type safety: strict typing, PHPStan level 9.

Installation

composer require pivotphp/http

Usage

Request

The router stores the matched route parameters as the route_params attribute on the PSR-7 request; ExpressRequest reads them.

use PivotPHP\Http\ExpressRequest;

$id     = $req->param('id');            // route parameter
$all    = $req->params();              // all route parameters
$page   = $req->query('page', '1');    // query string
$name   = $req->input('name');         // parsed body, then query string
$data   = $req->json();                // decoded JSON body (array)
$token  = $req->header('Authorization');
$secure = $req->isSecure();
$html   = $req->accepts('text/html');  // content negotiation (wildcards + q)

Response

Setters are fluent; terminal methods also update the wrapped response, so psr7() reflects the final state even without capturing the return value.

use PivotPHP\Http\ExpressResponse;

return $res->status(201)->header('X-App', 'PivotPHP')->json($data);
// or:
return $res->redirect('/login');
return $res->error(404, 'not found');

Body parsing

PHP only fills $_POST for POST requests, so JSON and form bodies on PUT/PATCH/DELETE are otherwise lost. Add BodyParsingMiddleware to the pipeline — it decodes JSON (application/json, application/*+json) and parses form bodies, populating getParsedBody():

use PivotPHP\Http\Middleware\BodyParsingMiddleware;

$app->use(new BodyParsingMiddleware());

A malformed JSON body throws MalformedJsonException, which implements HttpExceptionInterface (getStatusCode() returns 400) — catch it and return 400.

Parsing stays in the pipeline on purpose: ServerRequestFactory only builds the request, so the exception is raised where an error handler can turn it into a response.

Emitting the response

use PivotPHP\Http\Emitter\SapiEmitter;

(new SapiEmitter())->emit($response, $request->getMethod());

SapiEmitter sends the status line and headers once, streams the body in chunks, omits the body for HEAD and body-less statuses (1xx, 204, 304), and sets Content-Length when known.

API

PivotPHP\Http\ExpressRequest (wraps ServerRequestInterface)

Method	Description
params(): array	All matched route parameters.
param(string $name, mixed $default = null)	Route parameter.
query(string $name, mixed $default = null)	Query-string value.
input(string $name, mixed $default = null)	Parsed body, then query string.
json(): array	Decoded JSON body; throws MalformedJsonException on malformed input.
header(string $name, ?string $default = null)	Header line.
cookie(string $name, ?string $default = null)	Cookie value.
file(string $name)	Uploaded file.
ip(), userAgent(), method(), path()	Request metadata.
isAjax(), isJson(), isSecure(), accepts(string $type)	Checks.
psr7(): ServerRequestInterface	The underlying PSR-7 request.

PivotPHP\Http\ExpressResponse (wraps ResponseInterface)

Fluent setters return $this; terminal senders update the wrapped response and return it.

Method	Kind	Description
status(int $code)	setter	Set the status code.
header(string $name, string $value)	setter	Set a header.
cookie(string $name, string $value, array $options = [])	setter	Append Set-Cookie.
json(mixed $data, ?int $status = null)	sender	JSON response.
text(string $text, ?int $status = null)	sender	Plain-text response.
html(string $html, ?int $status = null)	sender	HTML response.
redirect(string $url, int $status = 302)	sender	Redirect.
noContent(int $status = 204)	sender	Empty response.
send(mixed $data, ?int $status = null)	sender	JSON for arrays/objects, text otherwise.
error(int $status, string $message = '')	sender	{"error": "..."} JSON.
psr7(): ResponseInterface	—	The wrapped PSR-7 response.

PivotPHP\Http\Factory\ServerRequestFactory

use PivotPHP\Http\ExpressRequest;
use PivotPHP\Http\Factory\ServerRequestFactory;

$request = ServerRequestFactory::fromGlobals();   // reads $_SERVER, $_GET, $_POST, $_FILES, ...
$request = ServerRequestFactory::fromArrays($server, $headers, $cookies, $get, $post, $files);
$req = new ExpressRequest($request);

The factory only builds the request; body parsing is done by BodyParsingMiddleware.
