Yesterday we have talked about converting URL into clickable link by Regular Expression.
PHP – Convert URL into clickable link by Regular Expression
If you want a more complete and robust solution, you can try the UrlLinker written by Søren Løvborg.
1. Download the UrlLinker.php @ kwi / urllinker
2. Try the following piece of code
<?php
require("UrlLinker.php");
$text = <<<EOD
Here's an e-mail-address:bob@example.org. Here's an authenticated URL: http://skroob:12345@example.com.
Here are some URLs:
stackoverflow.com/questions/1188129/pregreplace-to-detect-html-php
Here's the answer: http://www.google.com/search?rls=en&q=42&ie=utf-8&oe=utf-8&hl=en. What was the question?

There is no place like 127.0.0.1! Except maybe http://news.bbc.co.uk/1/hi/england/surrey/8168892.stm?

Beware of Greeks bringing internationalized top-level domains: xn--hxajbheg2az3al.xn--jxalpdlp.
10.000.000.000 is not an IP-address. Nor is this.a.domain.
<script>alert('Remember kids: Say no to XSS-attacks! Always HTML escape untrusted input!');</script>
EOD;
print(nl2br(htmlEscapeAndLinkUrls($text)));
?>
Done =)
