convert [url] to hyperlink?

[faheem786]

$patterns = array("/\[url\](.*)\[\/url\]/", "/\s(f|ht)(tps?:\/\/)(\S*)/", "/\[url=(.*)\](.*)\[\/url\]/");
$replaces = array("<a href=\"\\1\">\\1</a>", " <a href=\"\\1\\2\\3\">\\1\\2\\3</a>", "<a href=\"\\1\">\\2</a>");

$string = preg_replace($patterns, $replaces, $string);

Hi,

Can some one help me to make the above working for

www.yahoo.com (without [url]http://[/url])?

Thanks

Like this?

$string = preg_replace("/(?<!quot;|[=\"]|:\/\/)\b((\w+:\/\/|www\.).+?)"
."(?=\W*([<>\s]|$))/i", "<a href=\"$1\" target=\"_blank\">$1</a>", $string);
$string = preg_replace("/href=\"www/i", "href=\"http://www", $string);

HTH.
