**Warning: This is a pure proof of concept of a tweet-sized URL router**

**DO NOT USE IT IN PRODUCTION!**

```
class µ{static function __callStatic($n,$a){static$r;$n==@_?($_=@$r[getenv(REQUEST_METHOD).getenv(REQUEST_URI)])&&$_():$r[$n.$a[0]]=$a[1];}}
```

### How to use

[](#how-to-use)

**Step 1:** Define routes callbacks

```
µ::GET('/',function(){
    echo 'What is your name?';
    echo '';
});
```

```
µ::POST('/',function(){
    echo 'Hello ',$_POST['username'],', how are you?';
});
```

**Step 2:** Run the app

```
µ::_();
```

**Step 3:** Breath.

        // Check if we must resolve the request
        if($functionName == '_'){

            // Compose the method+uri key and
            // invoke the callback (silence failures)

            ($callback = @$callbackMap[getenv(REQUEST_METHOD).getenv(REQUEST_URI)]) && $callback();

        } else {

            // Add the route handler to the callbackMap
            // $functionName is the Request HTTP Method
            // $functionParameters[0] is the route
            // $functionParameters[1] is the callback

            $callbackMap[$functionName.$functionParameters[0]] = $functionParameters[1];
        }
