Snippet: Poor Mans PHP Routing

routing.php

<?php
// CONFIG: Path to Controllers, including trailing slash
$contollerPath = './Controllers/';


// If there is a query string, then get its position so it can be separated from the Controller/Method requested
if (strpos($_SERVER['REQUEST_URI'], '?')) {
    $queryOffset = strpos($_SERVER['REQUEST_URI'], '?') - ($_SERVER['REQUEST_URI'] + 1);
} else {
    $queryOffset = strlen($_SERVER['REQUEST_URI']);
}

// Parse the Route into an array
$route = substr($_SERVER['REQUEST_URI'], 1, ($queryOffset));
$route = explode('/', $route);

// Obtain the Controller and Method requested
$controller = $route[0];
$controllerMethod = $route[1];


if (file_exists($contollerPath . $controller . '.php')) {			// If the Controller file exists
    require_once($contollerPath . $controller . '.php');			// Include the Controller file
    if (class_exists($controller)) {								// If the Controller Class exists
        $tmpObject = new $controller;								// Instantiate the Controller
        if (is_callable(array($tmpObject, $controllerMethod))) {	// If the Method is able to be called
            call_user_func(array($tmpObject, $controllerMethod));   // Call the Method
        }
    }
}
