What is & good for? This can only be useful when looking in HTML or XML, right?
Title: What about the top level domain 'name'?

Comment:
The top level domain 'name' has a length of four characters. Therefor I believe '{2,3}' should be replaced by '{2,4}'.

A FQDN does in fact end with a dot.
Title: When the domain has (-) on it

I tried it on php but found a problem when there are dashes "-" on the domain name. Found the next workaround:
from:
[a-zA-Z0-9\-\.]
to:
[a-zA-Z0-9\.\-]
Change the . and - order
Thanks Michael, regards

I have made some small alterations. I am now using the following code:
function find_urls_in_text($string) {
$URL="((http|https|ftp)\://)?[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1,3})(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&%\$#\=~;])*";
$REGEX_LINK="[\s^(](".$URL."[^\.\,\)\(\s<])";
if ( preg_match_all("=$REGEX_LINK=", $string, $matches) )
return $matches[1];
else
return false;
}
Title: Works with IP addresses

^((http|https|ftp)\://)?[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1,3})(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&%\$#\=~])*[^\.\,\)\(\s]$
This slight alteration makes it work with IP addresses. Also, I added that the http:// (or similar) part be optional because that's what my application needed.

What about URLs containing IP addresses, such as:
http://127.0.0.1/blah/etc
Other than this (major) deficit, this is a great expression.

That regex doesn't seem to work for me on the tester here. Gets no matches.
What do the [[:<:]] and [[:>:]] do?

[[:<:]]((http|https|ftp)\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,10}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\.\,_\?\'/\\\+&%\$#\=~;])*)[[:>:]]
This expresion works much better
