Control access to class

Question

I am using a class and functions for a controller.
Consider the following URL:

http://localhost:8888/mvc/user/profile/1

The class is user and the function is profile.
What is the best technique for someone going to

http://localhost:8888/mvc/user/random

and getting redirected elsewhere if the function isn't present?
As I'm unsure about this, I don't know what extra information you may need?

Answer 1

create htaccess with

//Custom 404 errors
ErrorDocument 404 http://localhost:8888/mvc/user/profile/1

You will get more details about .htaccess from here

Answer 2

Why not use php itself ?

if(!function_exists($function)){
 return header("HTTP/1.0 404 Not Found");
}

You can also redirect with the header function. So you can also add more logic if needed without having to depend on .htaccess or som other mechanism.

Answer 3

使用神奇的方法__call()处理任意方法调用。
