php - Getting the parameters out of uri -

i setup simple router class extracts following

1. controller
2. action
3. parameters

class router {

private $uri; private $controller; private $method; private $params;  public function __construct($uri) {     $this->uri = $uri;     $this->method = 'index';     $this->params = array(); }  public function map() {     $uri = explode('/', $this->uri);     if (empty($uri[0])) {         $c = new config('app');         $this->controller = $c->default_controller;     } else {         if (!empty($uri[1]))             $this->method = $uri[1];         // how parameters??     } } 

}

that simple $router->map() can give me right controller, action , single parameter uri http://domain.com/users/edit/2

that quite okay, if needed store more parameters in url : http://domain.com/controller/action/param/param2/param3

how push them $parms if don't know how many parameters passed.

you know 1st 2 values of array controller , action, after param.

so use array_shift($uri) first 2 , remaining $uri params.

public function map() {     $uri = explode('/', $this->uri);      // shift element off beginning of array.      $controller = array_shift($uri);     $action = array_shift($uri);      // $uri variable not contain params.      if (empty($uri[0])) {         $c = new config('app');         $this->controller = $c->default_controller;     } else {         if (!empty($uri[1]))             $this->method = $uri[1];         // how parameters??     } }
