clickable urls problem

[rebelo]

I´m using the following code to parse urls from the messages
but when they do have a slash (like http://test.com/index.htm)
the urls gets a /> (like http://test.com/index.htm />) at the
end and the link continues untill the end of the message.

Would someone be so kind in checking if something could be done at the code

//begin PHP
function make_clickable($buffer) {
$buffer = eregi_replace("(^|[ \n\r\t])((http(s?)://)(www\.)?([a-z0-9_-]+(\.[a-z0-9_-]+)+)(/[^/ \n\r]*)*)","\\1<a href=\"\\2\" target=\"_blank\">\\2</a>", $buffer);
$buffer = eregi_replace("(^|[ \n\r\t])((ftp://)(www\.)?([a-z0-9_-]+(\.[a-z0-9_-]+)+)(/[^/ \n\r]*)*)","\\1<a href=\"\\2\" target=\"_blank\">\\2</a>", $buffer);
$buffer = eregi_replace("([a-z_-][a-z0-9\._-]*@[a-z0-9_-]+(\.[a-z0-9_-]+)+)","<a href=\"mailto:\\1\">\\1</a>", $buffer);
$buffer = eregi_replace("(^|[ \n\r\t])(www\.([a-z0-9_-]+(\.[a-z0-9_-]+)+)(/[^/ \n\r]*)*)","\\1<a href=\"http://\\2\" target=\"_blank\">\\2</a>", $buffer);
$buffer = eregi_replace("(^|[ \n\r\t])(ftp\.([a-z0-9_-]+(\.[a-z0-9_-]+)+)(/[^/ \n\r]*)*)","\\1<a href=\"ftp://\\2\" target=\"_blank\">\\2</a>", $buffer);
return $buffer;
}

?>
//end PHP

I use this:

$finds[] = "/\[url=(.*?)\](.*)\[\/url\]/is";
        $replaces[] = '<a href="$1">$2</a>';
        $finds[] = '/(\A|\s)((http|ftp)+(s)?:-(\\/\\/)((\\w|\\.)+)(\\/)?(\\S+)?)(\Z|\s)/i';
        $replaces[] = ' <a href="$1">$6</a> ';
        $comment_text = preg_replace($finds, $replaces, $comment_text);
