Note Submitter: erik at teshack dot com ---- I further refined the regular expression to support underscores in the URL as well as support a string that ends in a parenthesis, for example, (see: http://www.php.net) $content_text = preg_replace("/[^<> ]([a-zA-Z] +:\/\/[a-z][a-z0-9\_\.\-]*[a-z]{2,6}[a-zA-Z0-9\/ \*\_\.\-\?\&\%\=]*)([^\s|\)|\.|\,<])/i",'<a href= "$0" target="_blank">$0</a>',$content_text);
