Replacing URLs in string

[Anon]

Hi there,

i try to identify valid URLs in a simple string, and replace these parts with suitible HTML-tags, so that users can click on the URL in the text.

Example:
- blablabla http://www.domain.de
- blablabla <a href="http://www.domain.de">http://www.domain.de</a>

But: The script should also be able to identify the valid URL-Part, if there's a comma oder a dot at the end:

Example:
- blablabla http://www.domain.de, blabla...

or even if there's http:// missing:
- blablabla www.domain.de, blablalba

Is there anybody here who can figure this out?

Thanx so far, Christain

preg_replace(array("/( www.)/i","/(http:\/\/[^\ ]*)/i"),array("http://\$1","<a href=\"\\$1">\$1</a>"),$text);

the first replaces all www. to http://www...
and the second makes html tag

I'm not sure about \$1, so check php.net/preg_replace
