How to remove only links from string and nothing more

Question

I have string: Some text (some text) anylink.com www.anylink.com http://anylink.com R.I.O one-www.link.com

I have this code:

$pattern = "/[a-zA-Z]*[:\/\/]*[A-Za-z0-9\-_]+\.+[A-Za-z0-9\.\/%&=\?\-_]+/i";
$replacement = "";
$name = preg_replace($pattern, $replacement, $name);

It removes fine: anylink.com, www.anylink.com, http://anylink.com

But its also remove word R.I.O and one- how I can avoid this?

Thanks for help.

what makes the string "R.I.O" an invalid link? also, is this php? — Robson, May 04 '15 at 13:37
Yes it is PHP. I want that word R.I.O would not be removed because its not link also one- should not be removed either. — Karolis Toleikis, May 04 '15 at 13:44

Yes you are right in that case lets forget one- just about R.I.O problem than. — Karolis Toleikis, May 04 '15 at 14:05
do you want a regular expression to just work for that example string or do you want a regular expression to catch every possible URL? — Robson, May 04 '15 at 14:08
Every possible URL would be perfect. But I can also write down all domain extensions by hand if needed. — Karolis Toleikis, May 04 '15 at 14:14
That link is for links with html tag. My links don't have html tag they are like text. — Karolis Toleikis, May 04 '15 at 14:26

I believe that you should be sure of what is really a link or not you need to find a pattern

I realize that all your links may end with .com so try this regex "[a-zA-Z]*[:\/\/]*[A-Za-z0-9\-_]+\.+[A-Za-z0-9\.\/%&=\?\-_]+.com$"

but if you need .com.anything or .com/anything

"[a-zA-Z]*[:\/\/]*[A-Za-z0-9\-_]+\.+[A-Za-z0-9\.\/%&=\?\-_]+.com.*$"

I think this is more correct using your idea ([a-zA-Z]+[:\/\/]+)?[A-Za-z0-9\-_]+(\.[A-Za-z0-9\/%&=\?\-_]+)+ – Robson May 04 '15 at 14:15
