多个交换机语句

Question

Okay, I have one PHP file which needs to contain several switch($_GET['']) statements. For example: switch($_GET['id']), switch($_GET['open']), switch($_GET['number'])... Do I have to close it like:

switch($_GET['id'])
{

}

Or:

switch($_GET['open'])
{

};

One below another with or without semicolon?

This is my index.php:

It does not fully work. My php file is like this (Index.php):

<?php
// THE MAIN SITE
switch($_GET['open'])
{
    default: include("Home-Page.php");
    case 'Site': include("LetsStart/Pages/Home.php"); break;
    case 'Links: switch ($_GET['topics'])
    {
        default: include("LetsStart/Pages/Links.php"); break;
        case 'Tourism': include("LetsStart/Pages/Tourism.php"); break;
        case 'Finance': include("LetsStart/Pages/Finance.php"); break;
        case 'Health Care': include("LetsStart/Pages/HealthCare.php"); break;
    }
    break;
    case 'About Us': switch ($_GET['details'])
    {
        default: include("LetsStart/Pages/AboutUs.php"); break;
        case 'What We Do': include("LetsStart/Pages/WWD.php"); break;
        case 'Our History': include("LetsStart/Pages/OurHistory.php"); break;
    }
    break;
}
// ENCYCLOPEDIA
switch($_GET['letter'])
{
    case 'B': switch($_GET['term'])
    {
        default: include("LetsStart/Pages/TheEncyclopedia/Letter-B-Main.php"); break;
        case 'Term 1': include("LetsStart/Pages/TheEncyclopedia/B/1.php"); break;
        case 'Term 2': include("LetsStart/Pages/TheEncyclopedia/B/2.php"); break;
        case 'Term 2': include("LetsStart/Pages/TheEncyclopedia/B/3.php"); break;
    }
    break;
}
?>

It keeps loading my home page and the first page from the second switch.

You do not need a semicolon after the closing bracket of a switch statement (same as an if statement).
