Php, Fatal error: require(): Failed opening required

[gintare]

I am following the book "https://www.packtpub.com/":
https://www.packtpub.com/web-development/cms-design-using-php-and-jquery
On chapter one the give simple CMS example, but i am getting error when visit http://localhost/cms/

Warning: require(Page.php): failed to open stream: No such file or directory in C:\Bitnami\wampstack-5.4.38-0\apache2\htdocs\cms\ww.incs\basics.php on line 9

Fatal error: require(): Failed opening required 'Page.php' (include_path='.;C:/Bitnami/wampstack-5.4.38-0/php/PEAR;C:/Bitnami/wampstack-5.4.38-0/frameworks/smarty/libs') in C:\Bitnami\wampstack-5.4.38-0\apache2\htdocs\cms\ww.incs\basics.php on line 9.

The file C:\Bitnami\wampstack-5.4.38-0\apache2\htdocs\cms\ww.incs\basics.php

<?php
session_start();
function __autoload($name) {
line 9: require $name . '.php';
}
spl_autoload_register("__autoload");

I have added the line:
set_include_path($_SERVER['DOCUMENT_ROOT'].'/cms/ww.incs/');
Thus line 9 shifted to line 11:

function __autoload($name) {
line 11    require $name . '.php';
}
spl_autoload_register("__autoload");

But the error persists:
Warning: require(Page.php): failed to open stream: No such file or directory in C:\Bitnami\wampstack-5.4.38-0\apache2\htdocs\cms\ww.incs\basics.php on line 11

Fatal error: require(): Failed opening required 'Page.php' (include_path='C:/Bitnami/wampstack-5.4.38-0/apache2/htdocs/cms/ww.incs/') in C:\Bitnami\wampstack-5.4.38-0\apache2\htdocs\cms\ww.incs\basics.php on line 11

Seems the reason was that i by mistake commented out the last line of the file.
C:\Bitnami\wampstack-5.4.38-0\apache2\htdocs\cms1\ww.incs\basics.php

Full file, which now works:

<?php
session_start();
function __autoload($name) {
    require $name . '.php';
}
spl_autoload_register("__autoload");
 
/* added http://php.net/manual/en/function.spl-autoload-register.php */
/*throughs error, because there is not such a thing as Page.php
