How to detect a Link in a Forum or Guestbook?

[innu]

Hi,

I've made a guestbook on my side, but now I want, that if someone writes a Link it should detect it and make the html code for it.

Has anyone a solution for me?

sl,

what do you mean "if someone writes a link" ?
does it have to begin with http:// ? do you have a special input box ? a special tag ?

I mean:

someone writes in a textarea field, which I save in an Access DB the following:

http://www.google.com

or

http://www.google.com

I want that when I output this that it is a link:

<a href=&quot;

http://www.google.com&quot;

target=&quot;_blank&quot;>

http://www.google.com</a>

or
<a href=&quot;

http://www.google.com&quot;

target=&quot;_blank&quot;>

http://www.google.com</a>

I hope now you know what I meant

well then jsut detect every

http://www and

parse them
but what if the user enters an url WITHOUT

http://www (such

as imp.someprovider.com ??)
maybe you could check against a reg exp that detects xxx.xxx.xxx.xx ??? but then again what if the adress is only something.com ? detect all xxx.xx ? what if someone just writes some oo code like this.my_func ?
really you should make your users add a special tag - such as ... - then detect this tag and parse it
