A collection of small, focused, PSR-compliant PHP packages.
Compose only the pieces you need — every package stands on its own.

InitPHP publishes a family of independent, single-responsibility PHP packages. Each one solves a specific problem — HTTP messaging, routing, validation, sessions, etc. — and adheres to the relevant PHP-FIG standard (PSR-3, PSR-7, PSR-11, PSR-12, PSR-15, PSR-16, PSR-18 where applicable).

InitPHP is not a framework. There is no monolithic runtime, no opinionated bootstrap, no "you must structure your app like this". Take a router and nothing else; pair a query builder with a third-party DI container; or combine a dozen InitPHP packages to build something larger. The choice is yours.

If you have used the League of Extraordinary Packages or browsed Symfony's individual components, the model will feel familiar.

Every package is a standalone Composer install. There is no umbrella package to pull in — depend only on what you use.

composer require initphp/router

use InitPHP\Router\Router;

$router = new Router();

$router->get('/hello/{name}', function (string $name) {
    return "Hello, {$name}!";
});

$router->run();

The ecosystem has been streamlined: several narrow packages have been merged into broader, more capable ones, and a few stale wrappers have been retired. Composer surfaces the retired packages as abandoned and points you at the replacement.

Migration guides live in the README of each retired package.

Contributions are welcome and encouraged. Start with CONTRIBUTING.md for the workflow and conventions, browse open issues across the org for ideas, or open a Discussion if you want to talk through a larger change before sending a PR.

Security issues should be reported privately — see SECURITY.md.

If InitPHP saves you time, please consider sponsoring the project. Sponsorship directly funds active maintenance, security updates, CI/CD across the ecosystem, and improvements to initphp.org.
