I have a little code that its working perfectly fine but I would like to add a little feature so it remove cows.net at the bottom
its not removing cows.net because it doesn't have any text at the end
$str = 'text here google.com text here
text here http://cows.net/search/query?123 text here
text here cats.net text here
text here bird.org, text here
text here cows.net
text here';

$result = preg_replace('/(?:cows\.com|cats\.net|bird\.org)[, .]/i', '', $str);

echo $result;
