Thanks for the tutorial first of all.
Everything works fine except on thing for me.
$ctlr->$url[1]();
when I use the above line, error comes up. But if i do the following it works.
$a = $url[1];
$ctlr->$a();
Can you please tell me why this is happening?

I Solve this:

$ctlr = new $url[0]();
$string = str_replace('"', "", $url[1]);
$ctlr->$string($url[1]);

i faces the same error but actully it's a version problem
if you use wamp then it's ok, it doesn't show any erro .. or u should use older version of xampp
it doesn't work with new version xampp
otherwise storing the url[1] in variable which is the good process to do it, such as
$a = $url[1];
$ctlr->$a();
