Forgr - Simple PHP Function-to-API

Turn PHP functions into REST APIs with one line of code.

Write a function, register it, call it as an API.

Quick Example

<?php
// routes/hello.php
use Forgr\Core\Request;
use Forgr\Core\Response;

function hello(Request $request): Response {
    $data = $request->getBody();
    $name = $data['name'] ?? 'World';
    
    return Response::success(['message' => "Hello {$name}!"]);
}

// Register as API endpoint
post('hello');

Call it:

curl -X POST localhost:8080 \
  -H "X-Route: hello" \
  -d '{"name": "John"}'

Quick Start

composer create-project forgr/v1 my-api
cd my-api
php -S localhost:8080

Test the included example:

curl -X POST localhost:8080 -H "X-Route: user"

How It Works

1. Create a .php file in the routes/ folder
2. Write a function that takes Request and returns Response
3. Register it: get('function_name') or post('function_name')
4. Call via HTTP with X-Route: function_name header

Registration Functions

get('function_name');      // GET route
post('function_name');     // POST route
put('function_name');      // PUT route
delete('function_name');   // DELETE route
route('name', 'PATCH');    // Custom HTTP method

Request & Response API

Request Methods

$request->getBody()        // JSON body as array
$request->getQuery('key')       // URL parameter
$request->getMethod()      // HTTP method
$request->getBearerToken() // Authorization header

Response Methods

Response::success($data)       // 200 with data
Response::created($data)       // 201 Created
Response::error($msg, $code)   // Error response
Response::notFound()           // 404 Not Found

Response Format

{
  "success": true,
  "message": "Success",
  "data": { "your": "data" },
  "timestamp": "2025-08-09 14:00:00"
}
