Wildcards

The following options exist

• a: (alfabetic chars only)
• n: (numbers only)
• an: (alfanumeric chars only)
• w: (alfanumeric, dash and underscore only)
• ?: (optional parameters) - must be last part of the url
• *: (lazy loading) - must be last part of the url

How to use

// In this case the id may be a number
$router->add('/user/{n:id}', 'GET', 'App\Controllers\UserController::show');

// In this case the id may only contain alfabetic chars or numbers (or both)
$router->add('/user/{an:id}', 'GET', 'App\Controllers\UserController::show');

// Now we want everything behind docs/ in the page variable
// For example when we go to the url /docs/user/edit we will receive user/edit in the page variable
$router->add('/docs/{*:page}', 'GET', function($page) {
    // do something with $page
});

// Optional parameter example
$router->add('/hello/{a:name}/{?:lastname}', 'GET', function($name, $lastname = null) {
    // check if lastname is provided
    // if ($lastname) {...}
})
