I suppose you are using PHP with Apache, so you can easily do this by changing the settings of the server in the files .htaccess or httpd.conf.

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

Alternatively you can do this by sending a redirection header through PHP. This has to be done before any actual output is sent.

<?php
// Ensure the request goes through HTTPS
if (!$_SERVER['HTTPS']) {
  header("HTTP/1.1 301 Moved Permanently");
  header('Location: https://your-app');
  exit;
}
// Do the other stuff
