Calling a class

I am a newbie

I am trying to build a CMS as described in a book. There are 5 files so far and I am sure I copied the code exactly from the book as is but I get the following error when I ru the script:
Fatal error: Class 'Page' not found in /var/www/html/kvcms/index.php on line 11

So there are the handler index.php

<?php

// { common variables and functions
include_once('vv.inc/common.inc');
$page = isset($_REQUEST['page']) ? $_REQUEST['page'] : '';
$id = isset($_REQUEST['id']) ? (int) $_REQUEST['id'] : 0;
// }
// { get current page id
if (!$id) {
    if ($page) { // load by name
        $r = Page::getInstanceByName($page);
        if ($r && isset($r->id))
            $id = $r->id;
        unset($r);
    }
    if (!$id) { // else load by special
        $special = 1;
        if (!$page) {
            $r = Page::getInstanceBySpecial($special);
            if ($r && isset($r->id))
                $id = $r->id;
            unset($r);
        }
    }
}
// }
// { load page data
if ($id) {
    $PAGEDATA = (isset($r) && $r) ? $r : Page::getInstance($id);
} else {
    echo '404 thing goes here';
    exit;
}
// }
echo $PAGEDATA->body;

then you have the common include file that just calls the basics.php file and that is supposed to load the page.php file and reference the Page object. Which is clearly not happening. The book tells me that you can call and object (or load it) without including the file if you use an autoload function which is included here.

Where is the mistake please?

The basics.php file

<?php

session_start();
function _autoload($name) {
    require $name . '.php';
}

function dbInit() {
    if(isset($GLOBALS['db'])) return $GLOBALS['db'];
global $DBVARS;
$db = new PDO('mysql:host='. $DBVARS['hostname'] . '; dbname='. $DBVARS['db_name'].
        $DBVARS['username'], $DBVARS['password']);
$db->query('set name utf8');
$db->num_queries = 0;
$GLOBALS['db'] = $db;
return $db;
}
function dbQuery($query) {
    $db=dbinit();
    $q=$db->query($query);
    $db->num_queries++;
    return $q;
}
function dbRow($query) {
    $q = dbQuery($query);
    return $q->fetch(PDO::FETCH_ASSOC);
}
define('SCRIPTBASE', $_SERVER['DOCUMENT_ROOT'] . '/');
require SCRIPTBASE . '.private/config.php';
if(!defined('CONFIG_FILE'))
    define('CONFIG_FILE', SCRIPTBASE. '.private/config.php');
set_include_path(SCRIPTBASE. 'vv.php_classes' . PATH_SEPARATOR.get_include_path());

?>

the page.php file

<?php

class Page {

    static $instances = array();
    static $instancesByName = array();
    static $instancesBySpecial = array();

    function __construct($v, $byField = 0, $fromRow = 0, $pvq = 0) {
# byField: 0=ID; 1=Name; 3=special
        if (!$byField && is_numeric($v)) { // by ID
            $r = $fromRow ?
                    $fromRow :
                    ($v ?
                            dbRow("select * from pages where id=$v limit 1") :
                            array()
                    );
        } else if ($byField == 1) { // by name
            $name = strtolower(str_replace('-', '_', $v));
            $fname = 'page_by_name_' . md5($name);
            $r = dbRow("select * from pages where name like '"
                    . addslashes($name) . "' limit 1");
        } else if ($byField == 3 && is_numeric($v)) { // by special
            $fname = 'page_by_special_' . $v;
            $r = dbRow(
                    "select * from pages where special&$v limit 1");
        }
        else
            return false;
        if (!count($r || !is_array($r)))
            return false;
        if (!isset($r['id']))
            $r['id'] = 0;
        if (!isset($r['type']))
            $r['type'] = 0;
        if (!isset($r['special']))
            $r['special'] = 0;
        if (!isset($r['name']))
            $r['name'] = 'NO NAME SUPPLIED';
        foreach ($r as $k => $v)
            $this->{$k} = $v;
        $this->urlname = $r['name'];
        $this->dbVals = $r;
        self::$instances[$this->id] = & $this;
        self::$instancesByName[preg_replace(
                        '/[^a-z0-9]/', '-', strtolower($this->urlname)
                )] = & $this;
        self::$instancesBySpecial[$this->special] = & $this;
        if (!$this->vars)
            $this->vars = '{}';
        $this->vars = json_decode($this->vars);
    }

    function getInstance($id = 0, $fromRow = false, $pvq = false) {
        if (!is_numeric($id))
            return false;
        if (!@array_key_exists($id, self::$instances))
            self::$instances[$id] = new Page($id, 0, $fromRow, $pvq);
        return self::$instances[$id];
    }

    function getInstanceByName($name = '') {
        $name = strtolower($name);
        $nameIndex = preg_replace('#[^a-z0-9/]#', '-', $name);
        if (@array_key_exists($nameIndex, self::$instancesByName))
            return self::$instancesByName[$nameIndex];
        self::$instancesByName[$nameIndex] = new Page($name, 1);
        return self::$instancesByName[$nameIndex];
    }

    function getInstanceBySpecial($sp = 0) {
        if (!is_numeric($sp))
            return false;
        if (!@array_key_exists($sp, $instancesBySpecial))
            $instancesBySpecial[$sp] = new Page($sp, 3);
        return $instancesBySpecial[$sp];
    }

}

Any help is appreciated
