Classes

[Krizo]

I have a function that calls class methods based on the the url that you enter.

The code:

function bla(){
if($_GET['module'] != ""){
	if(!file_exists(MODULI . $_GET['module'] . ".php")) echo "Module does not exist";
	else{
		if(class_exists($_GET['module'])){
			if(method_exists(new $_GET['module'], $_GET['action'])){
				call_user_func(array($_GET['module'], $_GET['action']), $_GET);
			}else{
				echo "Function doesn't exist";
			}
		}
	}
}
}

URL example: "http://www.blabla.com/index.php?module=news&action=showNews

Are there any drawbacks (speed,...) implementing it this way?

You could maybe shave off a few hundred-thousandths of a second by doing it some other way, but why bother. This way seems to work well. Security would be the major matter, but if "MODULI" is a safe path, i.e. nothing dangerous in there for your users to invoke, that should be ok.

By the way, when I try to use "class_exists()" with the second argument (boolean), I get a "wrong parameter count" error and "__autoload" doesn't get called (PHP5). Have you seen that?
