README
A very small framework for efficiently writing PHP web applications. The framework focuses on productivity, and prioritizes that over the overengineering that most modern frameworks tend to prioritize.

Routing and request handling
Raw framework has a strong focus on performance and scalability. For this reason, the framework will not load or instantiate controllers unless they are needed.
A controller will be instantiated if a request is received for the "base route" for it. The base route is the shortest path that the controller will handle requests for.
Example base routes:
/users
will instantiate the controller with no arguments for the constructor./users/<id>
will instantiate the controller with id from the path passed to the constructor.
Multiple controllers can subscribe to the same routes; each controller has an internal router which will determine which method will be called for that controller.
Example controller
use Raw\Route;
class Users extends Raw\Controller {
#[Route("/")]
public function index() {
return "Lists all users";
}
#[Route("/:id")]
public function retrieve(int $id) {
return "User id $id";
}
/**
* A handler can be annotated with multiple routes
*/
#[Route("/:id", ["POST"])]
#[Route("/:id/edit", ["GET", "POST"])]
public function edit(int $id) {
return "Edit user id $id";
}
#[Route("/:id", ["DELETE"])]
#[Route("/:id/delete", ["GET", "POST"])]
public function delete(int $id) {
return "Delete user id $id";
}
}
When the class has been declared, you can mount the controller
Raw::router()->mount('/users', Users::class);
The controller will be loaded whenever the request URL matches
/users
. A request for /users/123
will invoke the User::retrieve()
method.
Configuration Reference
Raw framework is configured via environment variables. The following is a complete
reference of the environment variables the framework respects. All configuration options
are accessible via Raw::config()->*
variables.
- MYSQL_HOST: The hostname or IP address of your MySQL server.
- MYSQL_PORT: The port number your MySQL server is listening on. Defaults to 3306.
- MYSQL_DATABASE: The name of the MySQL database you want your application to connect to.
- MYSQL_USER: The username for your MySQL database.
- MYSQL_PASSWORD: The password for your MySQL database.
- MYSQL_CHARSET: The charset to use for your MySQL database connection. If not specified, the default charset used is "utf8mb4".
- HTTP_PROXY: Specifies the HTTP Proxy to be used for HTTP requests made by your application. If not specified, no proxy will be used.
- HTTP_CLIENT_TIMEOUT: The timeout (in seconds) for HTTP client requests. If not specified, the default timeout is set to 10 seconds.
- HTTP_CLIENT_USER_AGENT: The User-Agent string to use for HTTP client requests. If not specified, the default User-Agent string is 'Raw/1.0'.
