Sorry tedd, this is broken. It doesn't solve problems with runs of
greater than 2 newlines which is even in the example :) I would use
the following instead which is also line break agnostic with final
output in the style for your system:
<?php
$data = preg_replace( "#[\r\n]+#", PHP_EOL, $input );
?>
Cheers,

Rob:
It's not broken according to my "given", which was "If that is all
(i.e., removing double linefeeds), then this will do it:" My code
does exactly what was stated. I did not catch there were more than
two linefeeds in the OP's problem. Doing more was something I did not
address.
Also, the solution you provided works better this way: :-)
$input = preg_replace( "#[\r\n]+[[:space:]]+[\r\n]+#", "\n", $input );
$input = preg_replace( "#[\r\n]+#", PHP_EOL, $input );
$input = trim( $input );
Cheers,
tedd
