You'll want to either use the preg_*() functions or read the ereg*() docs to find the POSIX syntax. > Thanks in advance, > Dan Here's a very quick-and-dirty solution: preg_replace("/(\n\n)(.*?)(\n\n)/", '\1<b>\2</b>\3', $text); It doesn't check for the beginning of the text, so if the first item in the text is a headline, you'll either need to ensure that it has 2 newlines at the beginning, or test for that in the regex. The above just bolds any text which has 2 newlines on either side. -- +----------------------------------------------------------------+ |Torben Wilson <torben@php.net> Netmill iTech| |http://www.coastnet.com/~torben http://www.netmill.fi| |Ph: 1 250 383-9735 torben@netmill.fi| +----------------------------------------------------------------+
