Re: regex for multiple line breakes

That sounds very logical but does not work unfortunatelly. The result is the same. It removes all linebreakes but one. I would like to pass this one: --------- first line second third --------- But not this one: --------- third forth -------- Fernando Castillo Aparicio schrieb:

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 <merlin_x@fastmail.fm> Para: php-general@lists.php.net Enviado: mié,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.
