Ho scritto questo codice, ma al momento di aprirlo non mi visualizza il contenuto, ma non mi da errore.

Codice PHP:
<?php
    
if(isset($_GET['page'])) {
        if(
$_GET['page'] == anteprime){
            if(
$_GET['sez'] == 'xbox') {
                    include(
ROOT_PATH "xbox/list_anteprime.php");
                } elseif(
$_GET['sez'] == 'nintendo') {
                    include(
ROOT_PATH "nintendo/list_anteprime.php");
                } elseif(
$_GET['sez'] == 'play') {
                    include(
ROOT_PATH "play/list_anteprime.php");
                } else {
                    echo 
"";
                }
        } elseif(
$_GET['page'] == recensioni) {
            if(
$_GET['sez'] == 'xbox') {
                include(
ROOT_PATH "xbox/list_recensioni.php");
            } elseif(
$_GET['sez'] == 'nintendo') {
                include(
ROOT_PATH "nintendo/list_recensioni.php");
            } elseif(
$_GET['sez'] == 'play') {
                include(
ROOT_PATH "play/list_recensioni.php");
            } else {
                echo 
"";
            }
        } elseif(
$_GET['page'] == trucchi) {
            if(
$_GET['sez'] == 'xbox') {
                include(
ROOT_PATH "xbox/list_trucchi.php");
            } elseif(
$_GET['sez'] == 'nintendo') {
                include(
ROOT_PATH "nintendo/list_trucchi.php");
            } elseif(
$_GET['sez'] == 'play') {
                include(
ROOT_PATH "play/list_trucchi.php");
            } else {
                echo 
"";
            }
        } else {
            
// IN PRIMO PIANO
            
include(ROOT_PATH "home/inprimopiano.php");
            
// NEWS
            
include(ROOT_PATH "home/news.php");
            
// PROSSIME USCITE
            
include(ROOT_PATH "home/prossime_uscite.php");
        }
    }
?>
Cosa c'è che non va?
