a PHP micro URL router in only 140 bytes. (99 bytes in hardcore branch)
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]]=$a[1];}}Step 1: Define routes callbacks
µ::GET('/',function(){
echo 'What is your name?';
echo '<form method=post><input type=text name=username><input type=submit></form>';
});µ::POST('/',function(){
echo 'Hello ',$_POST['username'],', how are you?';
});Step 2: Run the app
µ::_();Step 3: Breath.
class µ {
public static function __callStatic($functionName,$functionParameters){
static $callbackMap;
// Check if we must resolve the request
if($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];
}
}
