PHP MVC Routing -> How do I convert uri array elements to a string useful for routing? -

summary of issues

i'm having minor issues routing in mvc framework making. code looks should work, somewhere there wrong way i've split requested uri array , assigned string variable. eliminated of errors popped up, moved on instancialize controller , get:

error log

class name must valid object or string in /home2/canforce/public_html/index.php on line 23 

index.php

//analyze request $request = new request(); //breaks uri array  //routing $router = new router(array($request)); //routes requested uri $router->route();  //instancialize , execute controller $controller = new $router->getcontroller(); $method = $router->getmethod(); $controller->$method(); 

request.php

class request { public function __construct() {     //separates uri array     $uri = explode('/',$_server['request_uri']);     $uri = array_filter($uri);      //stores requested controller uri     if($uri[0]!="") {         $request['controller'] = $uri[0];     }     else {         $request['controller'] = "home";//defaults home     }      //stores requested method uri     if(isset($uri[1])) {         $request['method'] = $uri[1];     }     else {         $request['method'] = "index";//defaults index     }      //stores requested arguments in array form     $count = count($uri);     $j=0;     for($i=2;$i<$count;$i++) {         $request['args'][j] = $request[i];         $j++;     }      return($request);     } } 

router.php

class router { private $language = null; private $controller; private $view; private $method; private $args = null; public function __construct($request) { //given requested uri in array form, stores in local variables     $this->controller = $request['controller'];     $this->method = $request['method'];     $this->args = $request['args']; } public function route() { //put requested uri forms can deal  } public function getlanguage() {     return $this->language; }    public function getcontroller() {     return $this->controller; }    public function getview() {     return $this->view; } public function getmethod() {     return $this->method; } public function getargs() {     return $this->args; } } 

any appreciated!

the issue having due way in trying assign properties of request router.

$router = new router(array($request)); 

here have given router argument array 1 element. request instance. you not casting array. i'm not sure if intent. because of not able access properties of request in array notation (such $request['controller]).

as is, router need modified router::__construct() correctly assigns parameters. e.g.

public function __construct($array)  {     $request = $array[0];      $this->controller = $request->getcontroller(); // no longer using array notation     $this->method = $request->getmethod();         // such $request['method']     //... } 

or

remove unneeded array wrapping request argument , type hint on argument in constructor:

$router = new router($request);  // router.php public function __construct(request $request)  {   $this->controller = $request->getcontroller(); // no longer using array notation   $this->method = $request->getmethod();         // such $request['method']   //... } 

also need store class name string before create new instance:

$classname = $router->getcontroller(); $controller = new $classname;
