router

A simple request router.

Install

Via Composer

$ composer require vakata/router

Usage

// create an instance
$router = new \vakata\router\Router();
$router
    ->get('/', function () { echo 'homepage'; })
    ->get('/profile', function () { echo 'user profile'; })
    ->group('/books/', function ($router) { // specify a prefix
        $router
            ->get('read/{i:id}', function ($matches) {
                // this method uses a named placeholder
                // when visiting /books/read/10 matches will contain:
                var_dump($matches); // 0 => books, 1 => read, 2 => 10, id => 10
                // placeholders are wrapped in curly braces {...} and can be: 
                //  - i - an integer
                //  - a - any letter (a-z)
                //  - h - any letter or integer
                //  - * - anything (up to the next slash (/))
                //  - ** - anything (to the end of the URL)

                // placeholders can be named too by using the syntax:
                // {placeholder:name}
                
                // placeholders can also be optional
                // {?optional}
            })
            // for advanced users - you can use any regex as a placeholder:
            ->get('{(delete|update):action}/{(\d+):id}', function ($matches) { })
            // you can also use any HTTP verb
            ->post('delete/{i:id}', function ($matches) { })
    })
    // you can also bind multiple HTTP verbs in one go
    ->add(['GET', 'HEAD'], '/path', function () { })
    // you can also use with() statements to execute some code if the begging of the URL is a match to the prefix
    ->with('user', function () { echo 1; })
        ->get('view', function () { /* 1 will be echoed */ })
        ->post('chat', function () { /* 1 will be echoed */ });

// there is no need to chain the method calls - this works too:
$router->post('123', function () { });
$router->post('456', function () { });

// you finally run the router
try {
    $router->run(
        parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH),
        $_SERVER['REQUEST_METHOD']
    );
} catch (\vakata\router\RouterNotFoundException $e) {
    // thrown if no matching route is found
}
