I have been without luck in finding a solution to this mystery. It works fine without URLS from the news site Reuters. Any help or suggestions would be greatly appreciated. URL/Source avail upon request.

$var = htmlspecialchars("$var", ENT_QUOTES);

This little snippit has made my day. Thank you all for your time folks. It was too late for me to edit the post or delete it so I thought I'd just post my resolution instead.
