New page new include "blah.php"

[Textahead]

Total newbie to php.
Im trying to make a page counter that counts the number of pages each visitor views and displays a new (include fb01.php) with each page visited
This my approch so far but it dosnt seem to work.

<?php
if ($freeb == 0) {include 'fb00.php' ; $freeb ++; }

if ($freeb == 1) {include 'fb01.php' ; $freeb ++; }

if ($freeb == 2) {include 'fb02.php' ; $freeb ++; }

if ($freeb == 3) {include 'fb03.php' ; $freeb ++ ; }

if ($freeb == 4) {include 'fb04.php' ; $freeb ++ ; }

if ($freeb == 5) {include 'fb05.php' ; $freeb ++ ; }
?>

I know I may be on totally the wrong path so if someone could help it would be much appreciated
