Answer 1

The file simple_html_dom.php is not where you're telling PHP to look for it.
require_once('../simple_html_dom.php');
To be safe, try using the full path instead of a relative path.
require_once('E:\wamp\www\in.com\components\simple_html_dom.php');
BTW, if the full path above is incorrect, then that is your problem. This is the path that PHP is trying.
To clarify: I'm only suggesting the OP switch to absolute paths to identify and confirm the source of the issue. Going to production with absolute paths is rarely a good idea.

Answer 2

require and include paths can be tricky in PHP. Try to use full paths when you can. You'll find $_SERVER['DOCUMENT_ROOT'] usefull for that.

Answer 3

Your inlude_path should contain ".", which means current directory.
But if you having troubles with including file by relative name, then just try to use absolute names, like require_once('E:\wamp\www\in.com\components\simple_html_dom.php');
But better it should be:
require_once 'E:/wamp/www/in.com/components/simple_html_dom.php';
