preg_replace with URL problem

I use a preg_replace to auto insert HTML links within paragraphs.

Here's what I currently use:

$pattern = "~(?!(?:[^<\[]+[>\]]|[^>\]]+<\/a>))(".preg_quote($find_keyword, '/').")\b~msUi";
$replacement = "<a href=\"http://$kw_url\" title=\"$find_keyword\">\$0</a>"; 
$article_content = preg_replace($pattern, $replacement, stripslashes($article_content), 1, $added );

It works great, except 1 problem:

It doesn't match and replace if the keyword is a URL.

If: $find_keyword="http://www.mysite.com/" it won't come up with any matches even though it's in the content.

I already tried escaping $find_keyword with preg_quote, which didn't make any different.

Any regex experts know a solution? Thanks.

You can run your find_keyword through 

$find_keyword=preg_quote("http://www.mysite.com/", '/');

The forward slashes in your $find_keywords are not escaped which is breaking the pattern.
