You can check for the anchor tag, that way you'll always get the url (maybe your string contains separate URLs).

$str = 'Hello World <a class="red" contenteditable="false" href="http://domainname.com/demo/forums/profile/test.name">Test </a>&nbsp;this is creating a problem';

preg_match_all("/<a.*?href\s*=\s*['\"](.*?)['\"]/", $str, $res, PREG_SET_ORDER);

foreach($res as $key => $val) {
    echo $val[1];
}
