Need some help with code

[Parker Clack]

I have set up a new profile field but it is allowing url's, etc. into that field.

I would I set it up to strip html and url's from the field?

Right now I am using which doesn't do much.

if($profilefieldname == "field15") 
    { 
     $profilefield['value'] = $strip_tags($userinfo["$profilefieldname"]); 
    }

Thanks for any help in advance.
