README
This easy to use router is a simple wrapper for the FastRoute library.
Install
Install using Composer.
composer require andrewcarteruk/simple-route ^0.2
Example Usage
use SimpleRoute\Route; use SimpleRoute\Router; $router = Router::fromArray([ new Route('GET', '/', 'handler1'), new Route('GET', '/{page}', 'handler2'), ]); try { $result = $router->match($_SERVER['REQUEST_METHOD'], $_SERVER['REQUEST_URI']); $handler = $result->getHandler(); $params = $result->getParams(); // ... } catch (SimpleRoute\Exception\NotFoundException $exception) { // ... } catch (SimpleRoute\Exception\MethodNotAllowedException $exception) { // ... }
Documentation
The following documentation is derived from the FastRoute documentation.
Routes are defined as an array of SimpleRoute\Route
objects that are passed to
SimpleRoute\Router::fromArray(array $routes)
.
SimpleRoute\Route
objects require a $method
, a $pattern
and a $handler
:
$route = new Route($method, $pattern, $handler);
The $method
is an uppercase HTTP method string for which a certain route
should match. It is possible to specify multiple valid methods using an array:
$routes = [ // This route new Route(['GET', 'POST'], '/test', 'handler'), // Is equivalent to these two routes together new Route('GET', '/test', 'handler'), new Route('POST', '/test', 'handler'), ];
By default the $pattern
uses a syntax where {foo}
specifies a placeholder
with name foo
and matching the regex [^/]+
. To adjust the pattern the
placeholder matches, you can specify a custom pattern by writing {bar:[0-9]+}
.
Some examples:
$routes = [ // Matches /user/42, but not /user/xyz new Route('GET', '/user/{id:\d+}', 'handler'), // Matches /user/foobar, but not /user/foo/bar new Route('GET', '/user/{name}', 'handler'), // Matches /user/foo/bar as well new Route('GET', '/user/{name:.+}', 'handler'), ];
Custom patterns for route placeholders cannot use capturing groups. For example
{lang:(en|de)}
is not a valid placeholder, because ()
is a capturing group.
Instead you can use either {lang:en|de}
or {lang:(?:en|de)}
.
Furthermore parts of the route enclosed in [...]
are considered optional, so
that /foo[bar]
will match both /foo
and /foobar
. Optional parts are only
supported in a trailing position, not in the middle of a route.
$routes = [ // This route new Route('GET', '/user/{id:\d+}[/{name}]', 'handler'), // Is equivalent to these two routes together new Route('GET', '/user/{id:\d+}', 'handler'), new Route('GET', '/user/{id:\d+}/{name}', 'handler'), // This route is NOT valid, because optional parts can only occur at the end new Route('GET', '/user[/{id:\d+}]/{name}', 'handler'), ];
The $handler
parameter does not necessarily have to be a callback, it could
also be a controller class name or any other kind of data you wish to associate
with the route. SimpleRoute only tells you which handler corresponds to your
URI, how you interpret it is up to you.
