Is there any way to prevent access to a page without viewing the home page?

Is there any way to prevent going to a page, unless the viewer has visited the front page?

So that if they try to access any page without viewing the front page they are automatically redirected to the main page?

I'd be willing to add a code to every single page.

You might use sessions.

On top of the main page

<?php
session_start();
$_SESSION['main'] = 1;
?>

On top of all the other pages

<?php
session_start();
if (!isset($_SESSION['main'])) {
   header("http://www.sitename.com/index.php");
   exit();
}
?>

Make sure to put this code before everything else in the script.

Does this require PHP 2 to work?

It should work fine with just the Basic version. ;)
