My problem being that I keep getting the error:
Fatal error: Cannot redeclare file_get_html() (previously declared in C:\wamp\www\seo\classes\simple_html_dom.php:37) in C:\wamp\www\seo\classes\simple_html_dom.php on line 41
which is due to the last function in the class get_actual_description().
Can anyone see where im cocking up?
regards,
Phil

Answer 1

put require_once "simple_html_dom.php" outside of function
