[PHP] Another preg question

[Al]

I'm trying to clean up newline code received from a browser textarea.

First, I'm normalizing the newline codes to Unix with:

$text= preg_replace("/(\r\n|\r)/", "\n", $text);                       
       //this seems to work OK

Next, I want to remove excessive CR/LF, [i.e. more than 2]

$text= preg_replace("/\n\n+/", "\n\n", $text);                         
   // remove excess This doesn't seem to do anything.

Thanks.....
