im working on a comment/forum app and when a user enters too many carriage returns i want to remove them before insert to db. example, user input: -----snip----- [quote=user] foo [/quote] <bunch of extra lines> more text... -----snip----- I to change to: [quote=user]foo[/quote] more text... i try this regexp: $message = preg_replace('#(\[quote(=(&quot;|"|\'|)([^\]]*)\\3)?\])\s+#i', "\\1\n", $_POST['message']); doesn't remove / replace anything. I need for it to work when they use [quote=xx] or [quote] and ends with [/quote] any help?

$str= preg_replace("%(\r\n|\r|\n)%", "\n", $str); $str= preg_replace("%\n\n+%", "\n\n", $str); //max 2 \n
