Turning multiple line breaks into one

[baris22]

Hello,

How can i change two or more than 2 line breaks into one?

I am using this for spaces and it works perfect but i do not know how to do for line breaks

$description = preg_replace('~[\r\n\s\t]+~', ' ', $description);

Edited

I did this and worked perfect

$to_replace = array("\r\n","|","\n","\\r\\n","\\n","&");
$description = str_replace($to_replace, "\n", $description);
$description = preg_replace('~[\n]+~', '<br>', $description);

You realise in that array you have "&" right? so your "&"'s will be replaced too...
