PHP Nano Framework

Pano is a nano(very small) framework designed around a single idea:

Define clear execution contracts, then provide simple default implementations.

The framework is intentionally minimal and non-opinionated. It gives developers structure without control, and contracts without restriction.

Design Philosophy

Pano is built on these principles:

• Absolute simplicity
• No hidden magic
• Full developer control
• Clear and explicit execution flow

Pano deliberately does not provide:

• ❌ MVC controllers
• ❌ A service container
• ❌ Global middleware

Instead, it provides:

• ✅ Execution contracts (Core)
• ✅ Stable default behavior (Foundation)
• ✅ Module-centric architecture

Core vs Foundation

Pano separates contracts from behavior.

Core

The Core contains only abstract base classes.

These classes:

• Define execution flow
• Define method signatures
• Define responsibilities
• Act as contracts, not implementations

All Core classes:

• Are abstract
• Use the Base prefix
• Are safe and intended to be extended

Core classes describe how the system works, not what it does.

Foundation

The Foundation contains final, concrete implementations built on top of Core contracts.

These classes:

• Implement Core behavior
• Provide sensible defaults
• Are production-ready
• Can be replaced or ignored entirely

Foundation exists for convenience, not enforcement.

        └── Request.php

Entry Point

All application execution starts from a single entry point:

(new \Pano\Foundation\Boot())->run();

You are free to replace Foundation\Boot with your own implementation.

BaseBoot (Core Contract)

abstract class BaseBoot
{
    abstract public function run(): void;

    protected BaseRequest $request;
}

• run() defines the execution flow
• Flow cannot be broken, only customized

BaseModule (Core Contract)

abstract class BaseModule
{
    public function __construct(
        protected BaseRequest $request
    ) {}

    abstract protected function routes(): BaseRouter;
}

Modules:

• Are the main execution units
• Receive a Request object
• Contain all business logic

Routing, validation, auth, and responses are fully controlled by the developer.

BaseRequest (Core Contract)

abstract class BaseRequest
{
    protected string|array $data;
    protected array $files;
    protected array $headers;
    protected array $queries;
    protected string $method;
    protected string $query;
    protected string $url;
    protected array $segments;
    protected string $host;
}

Advantages:

• No direct access to superglobals
• Predictable input
• High testability

BaseResponse (Core Contract)

abstract class BaseResponse
{
    abstract public function send(): void;

    protected int $status = 200;
    protected array $headers = [];
    protected mixed $body = null;
}

• send() is a closed execution flow

Error Handling

Error handling is intentionally simple.

Developers may:

• Catch exceptions inside Modules
• Override handleException() in Boot
• Introduce custom exception contracts

No global error strategy is enforced.

Environment (.env)

Pano supports a very simple .env file:

APP_NAME=Pano
APP_ENV=local
APP_KEY=Iur5UWL6KVz/2jsJTfjF+YbzAmnvejpIfYWo0fzZ8Mg=
APP_DEBUG=true
APP_URL=https://neda.tst
MODULE_RESOLVER=path #path or subdomain

The parser is minimal by design and intended for basic configuration only.

Suitable Use Cases

✔ MVP projects ✔ Small APIs ✔ Internal tools ✔ Personal frameworks ✔ Learning projects

❌ Large enterprise systems ❌ Large teams with strict standards

Summary

Pano is a framework that:

• Separates contracts from behavior
• Trusts developers over abstractions
• Avoids magic and global state
• Encourages clarity and ownership

A framework should guide execution, not control it.

Built for developers who prefer understanding to convenience 🧠
