README

AltoRouter is a small but powerful routing class for PHP 5.3+, heavily inspired by klein.php.

• Dynamic routing with named parameters
• Reversed routing
• Flexible regular expression routing (inspired by Sinatra)
• Custom regexes

Getting started

1. PHP 5.3.x is required
2. Install AltoRouter using Composer or manually
3. Setup URL rewriting so that all requests are handled by index.php
4. Create an instance of AltoRouter, map your routes and match a request.
5. Have a look at the example index.php file for a better understanding on how to use AltoRouter(index.php).

Routing

$router = new AltoRouter();
$router->setBasePath('/AltoRouter'); // (optional) the subdir AltoRouter lives in

// mapping routes
$router->map('GET|POST','/', 'home#index', 'home');
$router->map('GET','/users', array('c' => 'UserController', 'a' => 'ListAction'));
$router->map('GET','/users/[i:id]', 'users#show', 'users_show');
$router->map('POST','/users/[i:id]/[delete|update:action]', 'usersController#doAction', 'users_do');

// reversed routing
$router->generate('users_show', array('id' => 5));

You can use the following limits on your named parameters. AltoRouter will create the correct regexes for you.

*                    // 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, stops at the next trailing slash)
[*: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

@/(?[A-Za-z]{2}_[A-Za-z]{2})$ // custom regex, matches language codes like "en_us" etc.
/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

The character before the colon (the 'match type') is a shortcut for one of the following regular expressions

'i'  => '[0-9]++'
'a'  => '[0-9A-Za-z]++'
'h'  => '[0-9A-Fa-f]++'
'*'  => '.+?'
'**' => '.++'
''   => '[^/\.]++'

New match types can be added using the addMatchTypes() method

$router->addMatchTypes(array('cId' => '[a-zA-Z]{2}[0-9](?:_[0-9]++)?'));
