Try this and see how close you get:

Code:

$find = "[^<a.*?&gt;].*?(web design)+?.*?[^</a>]";
$string = "WEB DESIGN Web Design web design <a href='google.com'>Web design las vegas</a>";
$finalstring = preg_replace('/('.$find.'\b)/iU', '<a href="http://google.com">\1</a>', $string,-1,$i);
echo $finalstring;
echo '<br />'.$i;
