Removing html anchors from POST'ed text string

[Dariusz]

I am having problems with trying to remove some tags using PHP. What I
want is to perform a search and replace on a URL, so if someone tried to
put a URL into a guestbook database, instead of the user inputting a
link as:

<a href="http://whatever.com">v isit me</A>

It goes into the database as:

http://whatever.com

I have tried the str_replace() function, but doesn't seem to work. I have
also tried strip_tags() but then that just give the result:

visit me

This is the code I've written.

$AmendedComment = str_replace("<a href=\"", " ", $_POST['Comment']);
$FinalComment = addslashes($Ame ndedComment);

Checking the database and reading it out again, the first part of the URL
remains intact, so the URL is clickable - not what I want.

I've made an attempt at preg_replace() but it's difficult to get head
around trying to write a pattern.

Any help appreciated.

First attempt (I checked that it works on your example, I didn't try
anything else):

$href = '<a href="http://whatever.com">v isit me</A>';
$unclickable_ur l = preg_replace('! <a.+?href="([^"]+)".*?</a>!i', "$1",
$href);
echo $unclickable_ur l;

I'm sure this is not good enough yet. Feel free to improve, anyone.
