Stripping a Link URL from a Comment (textarea)

How can I search and strip a link URL from a comment post and replace it with something like
http://www.mydomain.com/redirect.php?c=http://www.poster_domain.com&a=123
Poster's URL link can have a query string (?)

or

http://www.mydomain.com/redirect.php?c=http://www.poster_domain.com

 

anyone?...

 

how does the comment looks like?

just "this is some text and my website is astrazone.com"

or "this is some other text but my website is still <a href="astrazone.com">astrazone.com</a>"

 

i think u need to use reg exp and replace all occurrence of anchor tags with your url proxy

 

$pattern = '/(<a[^>]*? href=")([^"]+)/si';
function href_adjuster($matches) {
    return $matches[1].'http://www.mydomain.com/redirect.php?c='.urlencode($matches[2]);
}

$text = preg_replace_callback($pattern, 'href_adjuster', $text);

PHP:

This will urlencode the redirecting href, so you will need to do urldecode($_GET['c']) in redirect.php to get it back to the original

 

if you still don't have it, i can make you such a php script but for $$$, if you are interested, just PM me how much you are willing to pay.

 

Why would he pay when I've given the solution above???

 

sry... i didn't red the whole thread only the title and just replayed. :S sry...
