This is a dimple(damn simple) URL routing script for PHP which is written in just 140 characters of code, so it fits within a tweet.
Its NOT a good router at all, don't use it on a real application, its not exception handled either. I did it just for fun and to demonstrate the simplicity
So here's the router code, and that's all (seriously).
class R{
function a($r,callable $c){$this->r[$r]=$c;}
function e(){$s=$_SERVER;$i='PATH_INFO';$p=isset($s[$i])?$s[$i]:'/';$this->r[$p]();}
}Create a file index.php in your server root and try this code
<?php
// The router code
class R{
function a($r,callable $c){$this->r[$r]=$c;}
function e(){$s=$_SERVER;$i='PATH_INFO';$p=isset($s[$i])?$s[$i]:'/';$this->r[$p]();}
}
//
// Create
$router = new R();
// Add a route with a callback function
$router->a('/a', 'callbackFunction');
// Add a route with a closure
$router->a('/b', function(){
echo 'Hello B';
});
// Add homepage route
$router->a('/', function(){
echo 'Hello World';
});
// Add route with class method
$router->a('/c', [new Foo, 'bar']);
// Add multiple slashed route with class method
$router->a('/c/d', [new Foo, 'bar']);
// Execute the route
$router->e();
// Callback handlers
function callbackFunction(){
echo 'Hello A';
}
class Foo{
function bar(){
echo 'Hello Bar';
}
}Now visit your server root http://localhost/index.php, http://localhost/index.php/a, http://localhost/index.php/b, http://localhost/index.php/c and http://localhost/index.php/c/d.
Or you may run built-in PHP ser 4B58 ver from the command line (in the same dir)
php -S localhost:8081
and visit http://localhost:8081/index.php.
Runs on 5.4+. 140 chars idea is inspired by Fabien Potencier's Twittee.
