Simple PHP Router

Hey! This is a simple and small single class PHP router that can handle the whole URL routing for your project. It utilizes RegExp and PHP's anonymous functions to create a lightweight and fast routing system. The router supports dynamic path parameters, special 404 and 405 routes as well as verification of request methods like GET, POST, PUT, DELETE, etc. The codebase is very small and very easy to understand. So you can use it as a boilerplate for a more complex router.

Take a look at the index.php file. As you can see the Route::add() method is used to add new routes to your project. The first argument takes the path segment. You can also use RegExp in there to parse out variables. All matching variables will be pushed to the handler method defined in the second argument. The third argument will match the request method. The default method is 'get'.

Simple example:

// Require the class
include 'src\Steampixel\Route.php';

// Use this namespace
use Steampixel\Route;

// Add the first route
Route::add('/user/([0-9]*)/edit', function($id) {
  echo 'Edit user with id '.$id.'<br>';
}, 'get');

// Run the router
Route::run('/');

You will find a more complex example with a build in navigation in the index.php file.

Installation using Composer

Just run composer require steampixel/simple-php-router Than add the autoloader to your project like this:

// Autoload files using composer
require_once __DIR__ . '/vendor/autoload.php';

// Use this namespace
use Steampixel\Route;

// Add your first route
Route::add('/', function() {
  echo 'Welcome :-)';
});

// Run the router
Route::run('/');

Use a different basepath

If your script lives in a subfolder (e.g. /api/v1) set this basepath in your run method:

Route::run('/api/v1');

Do not forget to edit the basepath in .htaccess too if you are on Apache2.

Enable case sensitive routes, trailing slashes and multi match mode

The second, third and fourth parameters of Route::run('/', false, false, false); are set to false by default. Using this parameters you can switch on and off several options:

• Second parameter: You can enable case sensitive mode by setting the second parameter to true.
• Third parameter: By default the router will ignore trailing slashes. Set this parameter to true to avoid this.
• Fourth parameter: By default the router will only execute the first matching route. Set this parameter to true to enable multi match mode.

Something does not work?

• Don't forget to set the correct basepath as the first argument in your run() method and in your .htaccess file.
• Enable mod_rewrite in your Apache2 settings, in case you're using Apache2: a2enmod apache2

Test setup with Docker

I have created a little Docker test setup.

1. Build the image: docker build -t simplephprouter docker/image-php-7.2

2. Spin up a container

   • On Linux / Mac or Windows Powershell use: docker run -d -p 80:80 -v $(pwd):/var/www/html --name simplephprouter simplephprouter
   • On Windows CMD use docker run -d -p 80:80 -v %cd%:/var/www/html --name simplephprouter simplephprouter

3. Open your browser and navigate to http://localhost

Themes, layouts, pages and components
