Extract URLs from text in PHP

Question

I have this text:

$string = \"this is my friend\'s website http://example.com I think it is coll\";

How can I extract the link into another

URLs have a quite complex definition — you must decide what you want to capture first. A simple example capturing anything starting with http:// and https:// could be:

preg_match_all('!https?://\S+!', $string, $matches);
$all_urls = $matches[0];

Note that this is very basic and could capture invalid URLs. I would recommend catching up on POSIX and PHP regular expressions for more complex things.
