You are replacing 1 or more matchs of a new line. To match 2 or more you can use "{2,}". It's a range, first number means min matches, second max matches. Omitting last number means no max limit.
$data[txt] = preg_replace('`[\r\n]{2,}`',"\n",$data[txt]); ________________________________ De: Merlin Morgenstern <merli...@fastmail.fm> Para: php-general@lists.php.net Enviado: miƩ,14 octubre, 2009 12:17 Asunto: [PHP] regex for multiple line breakes Hi there, I am trying to remove multiple linebreakes from a textarea input. Spammers tend to insert multiple line breakes. The problem is, that I want to allow 2 line breaks so basic formating should be allowed. I am doing this by regex: $data[txt] = preg_replace('`[\r\n]+`',"\n",$data[txt]); I would need a regex that allows \r\n\r\n, but not more than this.
