README

• Flexible regular expression routing (inspired by Sinatra)
• A set of boilerplate methods for rapidly building web apps
• Almost no overhead => 2500+ requests/second

Getting started

1. PHP 5.6.x is required
2. Install Router using Composer (recommended) or manually
3. Setup URL rewriting so that all requests are handled by index.php
4. (Optional) Throw in some APC for good measure

Composer Installation

1. Get Composer
2. Require Router with php composer.phar require gabrielbull/router
3. Install dependencies with php composer.phar install

Example

Hello World - Obligatory hello world example

<?php
require_once __DIR__ . '/vendor/autoload.php';

$router = new \Router\Router();

$router->respond('GET', '/hello-world', function () {
    return 'Hello World!';
});

$router->dispatch();

Example 1 - Respond to all requests

$router->respond(function () {
    return 'All the things';
});

Example 2 - Named parameters

$router->respond('/[:name]', function ($request) {
    return 'Hello ' . $request->name;
});

Example 3 - So RESTful

$router->respond('GET', '/posts', $callback);
$router->respond('POST', '/posts', $callback);
$router->respond('PUT', '/posts/[i:id]', $callback);
$router->respond('DELETE', '/posts/[i:id]', $callback);
$router->respond('OPTIONS', null, $callback);

// To match multiple request methods:
$router->respond(array('POST','GET'), $route, $callback);

// Or you might want to handle the requests in the same place
$router->respond('/posts/[create|edit:action]?/[i:id]?', function ($request, $response) {
    switch ($request->action) {
        //
    }
});

Example 4 - Sending objects / files

$router->respond('/report/latest', function ($request, $response) { $response->file('/tmp/cached_report.zip'); });

## Route namespaces

```php
$router->with('/users', function () use ($router) {

    $router->respond('GET', '/?', function ($request, $response) {
        // Show all users
    });

    $router->respond('GET', '/[:id]', function ($request, $response) {
        // Show a single user
    });

});

foreach(array('projects', 'posts') as $controller) {
    // Include all routes defined in a file under a given namespace
    $router->with("/$controller", "controllers/$controller.php");
}

Included files are run in the scope of Router ($router) so all Router methods/properties can be accessed with $this

Example file for: "controllers/projects.php"

// Routes to "/projects/?"
$this->respond('GET', '/?', function ($request, $response) {
    // Show all projects
});

Routing

[ match_type : param_name ]

Some examples

*                    // Match all request URIs
[i]                  // Match an integer
[i:id]               // Match an integer as 'id'
[a:action]           // Match alphanumeric characters as 'action'
[h:key]              // Match hexadecimal characters as 'key'
[:action]            // Match anything up to the next / or end of the URI as 'action'
[create|edit:action] // Match either 'create' or 'edit' as 'action'
[*]                  // Catch all (lazy)
[*:trailing]         // Catch all as 'trailing' (lazy)
[**:trailing]        // Catch all (possessive - will match the rest of the URI)
.[:format]?          // Match an optional parameter 'format' - a / or . before the block is also optional

Some more complicated examples

/posts/[*:title][i:id]     // Matches "/posts/this-is-a-title-123"
/output.[xml|json:format]? // Matches "/output", "output.xml", "output.json"
/[:controller]?/[:action]? // Matches the typical /controller/action format

Note - all routes that match the request URI are called - this allows you to incorporate complex conditional logic such as user authentication or view layouts. e.g. as a basic example, the following code will wrap other routes with a header and footer

$router->respond('*', function ($request, $response, $service) { $service->render('header.phtml'); });
//other routes
$router->respond('*', function ($request, $response, $service) { $service->render('footer.phtml'); });

Routes automatically match the entire request URI. If you need to match only a part of the request URI or use a custom regular expression, use the @ operator. If you need to negate a route, use the ! operator

// Match all requests that end with '.json' or '.csv'
$router->respond('@\.(json|csv)$', ...

// Match all requests that _don't_ start with /admin
$router->respond('!@^/admin/', ...

Generate url

First, you have to instantiate a path generator and inject a router instance and (optionally) a domain prefix.

$router = new \Router\Router();
$pathGenerator = new \Router\PathGenerator($router, 'http://www.domain.com');

To generate an url from a route, you have to give a name to the route.

$this->respond('GET', '/route/[:foo]', function ($request, $response) {
    // Handling route here
})->setName('packageName:routeName');

You can generate an url with the generate metod. The first argument is the name of the route followed by an array containing the url parameters. Finally, you can set $absolute (3rd parameter) to false to generate a relative path (default).

[ url parameters : value ]

$pathGenerator->generate('packageName:routeName', [
    'foo' => 'bar',
], true);

// return : http://www.domain.com/bar

You can add the pathGenerator into your favorite template engine and use it like this :

{{ path.generate('homepage') }}

API
