note 29626 added to function.preg-replace

Yet another URL hyperlinking preg! - Finds all possible protocols: http ftp https chrome irc etc... - Ignores links which come after a = or " so href=", href= and the like are not linked - Finds URLs beginning with www. - Accepts all URL special chars, even rarely used ones like | , # ( or ) - Links URLs that are at the very beginning and/or end of a string. - Won't link ending . , ? ! etc. characters ie. http://www.someurl.com! becomes <a href="http://www.someurl.com">http://someurl.com</a>! function addLinks($string) { $string = preg_replace("/(^|[^=\"\/])\b((\w+:\/\/|www\.)[^\s<]+)". "((\W+|\b)([\s<]|$))/i", "$1<a href=\"$2\">$2</a>$4", $string); return preg_replace("/href=\"www/i", "href=\"http://www", $string); } Of course, like any URL linking preg, there are always ways to trip it up. In this case, if you end a URL with more than one . , ? or ! (like: http://www.someurl.com???) it will include all but the last one in the link. I'm sure there are other ways too...
