README

Macaw is a simple, open source PHP router. It's super small (~150 LOC), fast, and has some great annotated source code. This class allows you to just throw it into your project and start using it immediately.

Install

If you have Composer, just include Macaw as a project dependency in your composer.json. If you don't just install it by downloading the .ZIP file and extracting it to your project directory.

require: {
    "noahbuscher/macaw": "dev-master"
}

Examples

First, use the Macaw namespace:

use \NoahBuscher\Macaw\Macaw;

Macaw is not an object, so you can just make direct operations to the class. Here's the Hello World:

Macaw::get('/', function() {
  echo 'Hello world!';
});

Macaw::dispatch();

Macaw also supports lambda URIs, such as:

Macaw::get('/(:any)', function($slug) {
  echo 'The slug is: ' . $slug;
});

Macaw::dispatch();

You can also make requests for HTTP methods in Macaw, so you could also do:

Macaw::get('/', function() {
  echo 'I <3 GET commands!';
});

Macaw::post('/', function() {
  echo 'I <3 POST commands!';
});

Macaw::dispatch();

Lastly, if there is no route defined for a certain location, you can make Macaw run a custom callback, like:

Macaw::error(function() {
  echo '404 :: Not Found';
});

If you don't specify an error callback, Macaw will just echo 404.

In order to let the server know the URI does not point to a real file, you may need to use one of the example configuration files.

Example passing to a controller instead of a closure

It's possible to pass the namespace path to a controller instead of the closure:

For this demo lets say I have a folder called controllers with a demo.php

index.php:

require('vendor/autoload.php');

use NoahBuscher\Macaw\Macaw;

Macaw::get('/', 'Controllers\demo@index');
Macaw::get('page', 'Controllers\demo@page');
Macaw::get('view/(:num)', 'Controllers\demo@view');

Macaw::dispatch();

demo.php:

<?php
namespace controllers;

class Demo {

    public function index()
    {
        echo 'home';
    }

    public function page()
    {
        echo 'page';
    }

    public function view($id)
    {
        echo $id;
    }

}

This is with Macaw installed via composer.

composer.json:

{
   "require": {
        "noahbuscher/macaw": "dev-master"
    },
    "autoload": {
        "psr-4": {
            "" : ""
        }
    }
}

.htaccess(Apache):

RewriteEngine On
RewriteBase /

# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ index.php?$1 [QSA,L]

.htaccess(Nginx):

rewrite ^/(.*)/$ /$1 redirect;

if (!-e $request_filename){
	rewrite ^(.*)$ /index.php break;
}
