I think I have no unnecessary new lines now.

This time I split search_send_header() into search_send_header() and print_search_heading(), because it will allow me to place a function between the Header and the full results Heading on the frontend/php/search/index.php. If I place a function before the original search_send_header() function on index.php it will appear at the top of the page and not inside the body.

Not sure if it did the trick for it, but I did use that function and it accepts the array fine. I am not very good at testing SQL bad stuff either.
