replacing 1> crlfs

[brendan]

Hi,
recieving mail from various mail clients ... some for some reason put
anything up to 4 or 5 carriage breaks in some parts of message ...
ie /n/n/n/n (sometimes spaces in between ie /n/n /n/n)
or /r/r/r/r
so I need to replace any repeated line breaks with just one line break

any ideas?
cheers

It's actually \n\n\n\n or \r\r\r\r (notice the backslash).

$msg = preg_replace("/[\r\n][\s]+/", "\r\n", $msg);
