php plugin / include issue

I'm trying to make a plugin system for one of my apps but I'm having a bit of trouble.

I'm trying to figure out how to dynamically add additional switch blocks to a switch statement using a plugin class.

Here's a basic example of what I'm trying to do, does anyone know how I could accomplish this?

switch($_GET['section']){
    default:
        // code here
    break;

    case 'test':
        // code here
    break;

    $plugins->run('page');

}

class plugins {
    function run($section){
        if($section=='page'){
            case 'test2':
                // code here
            break;
        }
    }       
}

The case statement in the plugin开发者_运维知识库s class is what I'd like to be returned to the original switch statement. So in the plugin class I can add additional cases that can be included in the original switch statement.

So I think basically just wondering if its possible to dynamically add additional cases to the switch statement.

I think you can better achieve what you are trying to do by using classes and inheritance.

This is wrong syntax:

if($section=='page'){ // WRONG!
    case 'test2':
       // code here
   break;
}

You can do it like this:

switch ($section) {
    case 'page':
         switch ($whatever) {      
              case 'test':
                   // do something
              break;
         }
    break;

    default:
        // do default stuff
    break;
}

It is always a good idea to use switch instead of if else!
