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,

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.
Actually, his comment didn't say double line feeds... his comment said
I want THIS to look like THAT. And THIS had a triple line feed and
THAT completely normalized it to a single line feed. I realize you
misunderstood the problem, but where I work, clients don't think a
solution based on incorrect presumptions is a valid solution for a
clearly defined problem :)
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 );
preg_replace( "/(\s)\s+/im", '\\1', $input );
:)
ahh just read the rest of this thread.. icnase it gets a bit pedantic
then here's a horizontal white space only one:
preg_replace( "/(\h)\h+/im", '\\1', $input );
and vertical only:
preg_replace( "/(\v)\v+/im", '\\1', $input );
(spot a pattern?)
Best,
Nathan
