Parameters in Custom Router PHP - php

Question

I am trying to create a custom router.
This is what I have so far:
<?php
/**
* Created by 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 a collection of internal GET URLs to look for
* #param $uri - The url that the user types in the browser
* #param $controller - The controller that will handle the url
* #param $method - The method of the controller that will run
*/
public function get($uri, $controller, $method)
{
$this->_getUri[] = $uri;
$this->_getController[] = $controller;
$this->_getMethod[] = $method;
}
/**
* Build a collection of internal POST URLs to look for
* #param $uri - The url that the user types in the browser
* #param $controller - The controller that will handle the url
* #param $method - The method of the controller that will run
*/
public function post($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 the url
var_dump($path);
foreach ($this->_getUri as $key => $value)
{
if (preg_match("#^$value$#", $path))
{
// echo $key . ' => ' . $value; //See what the $path returns
//Instantiate Controller
$controller = 'Fab\Controllers\\' . $this->_getController[$key];
$controller = new $controller();
//Call the appropriate method
$method = $this->_getMethod[$key];
$controller->$method();
}
}
} elseif ($_SERVER['REQUEST_METHOD'] === 'POST') {
$path = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH); //get the url
foreach ($this->_postUri as $key => $value)
{
if (preg_match("#^$value$#", $path))
{
//echo $key . ' => ' . $value; //See what the $path returns
//Instantiate Controller
$controller = 'Fab\Controllers\\' . $this->_postController[$key];
$controller = new $controller();
//Call the appropriate method
$method = $this->_postMethod[$key];
$controller->$method();
}
}
}
}
}
This allows me to say in my index.php something like:
$router->get('/portfolio', 'MainController', 'portfolio');
What I want to do now is to create an individual page for every item in the portfolio and give it a unique URL.
For example, if I have the item 'dinosaur' in my portfolio, I want to be able to say:
$router->get('/portfolio/dinosaur', 'MainController', 'searchIfDinosaurExistsInDatabase');
So generally, I would like to have in my index sth like:
$router->get('/portfolio/{item}', 'MainController', 'searchInDbForItem');
How can I modify my router in order to achieve this?

Answer 1

You need to add an regular expression to route. For example like this (it's a very simple example):
$router->get('/portfolio/[\w\d]+', 'MainController', 'searchInDbForItem');`
And you need use preg_match for comparison a route and an url.
It's a very simple example of router https://github.com/newage/example/blob/master/core/Route/HttpRoute.php
