model view controller - Parameters in Custom Router PHP -

i trying create custom router. have far:

<?php /**  * created phpstorm.  * user: antony  * date: 5/30/16  * time: 3:31 pm  */ namespace fab\router;  class router {     private $_geturi = array();     private $_getcontroller = array();     private $_getmethod = array();     private $_posturi = array();     private $_postcontroller = array();     private $_postmethod = array();  public function __construct() { }  /**  * build collection of internal urls  * @param $uri - url user types in browser  * @param $controller - controller handle url  * @param $method - method of controller run  */ public function get($uri, $controller, $method) {     $this->_geturi[] = $uri;     $this->_getcontroller[] = $controller;     $this->_getmethod[] = $method; }  /**  * build collection of internal post urls  * @param $uri - url user types in browser  * @param $controller - controller handle url  * @param $method - method of controller run  */ public function post($uri, $controller, $method) {     $this->_posturi[] = $uri;     $this->_postcontroller[] = $controller;     $this->_postmethod[] = $method; }  public function submit() {      if ($_server['request_method'] === 'get') {          var_dump($_server['request_uri']);         echo "\n";            $path = parse_url($_server['request_uri'], php_url_path); //get url          var_dump($path);          foreach ($this->_geturi $key => $value)         {             if (preg_match("#^$value$#", $path))             {  //                    echo $key . ' => ' . $value; //see $path returns                  //instantiate controller                 $controller = 'fab\controllers\\' . $this->_getcontroller[$key];                 $controller = new $controller();                  //call appropriate method                 $method = $this->_getmethod[$key];                 $controller->$method();             }         }     } elseif ($_server['request_method'] === 'post') {          $path = parse_url($_server['request_uri'], php_url_path); //get url          foreach ($this->_posturi $key => $value)         {             if (preg_match("#^$value$#", $path))             {                 //echo $key . ' => ' . $value; //see $path returns                  //instantiate controller                 $controller = 'fab\controllers\\' . $this->_postcontroller[$key];                 $controller = new $controller();                  //call appropriate method                 $method = $this->_postmethod[$key];                 $controller->$method();             }         }     }  }  } 

this allows me in index.php like:

$router->get('/portfolio', 'maincontroller', 'portfolio');

what want create individual page every item in portfolio , give unique url. example, if have item 'dinosaur' in portfolio, want able say: $router->get('/portfolio/dinosaur', 'maincontroller', 'searchifdinosaurexistsindatabase');

so generally, have in index sth like: $router->get('/portfolio/{item}', 'maincontroller', 'searchindbforitem');

how can modify router in order achieve this?

you need add regular expression route. example (it's simple example):

$router->get('/portfolio/[\w\d]+', 'maincontroller', 'searchindbforitem');` 

and need use preg_match comparison route , url.

it's simple example of router https://github.com/newage/example/blob/master/core/route/httproute.php
