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.

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.
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?)


Hi Nathan,
You may want to start testing your solutions. None have worked yet. Not even close :)

I think I see an issue... either my client, your client, both, or the PHP list is trimming email lines. I have spaces at the end of some of the lines in my example. Let's see if a text file attachment works for this. 

FYI my command-line is currently running 5.2.11

Yes it was client stripping out extra whitespace! thanks Rob, replicated your results: 
1
2 3
4
 5 6

and then 'fixed' to give what's needed:
  preg_replace( "/(((\r|)\n)(\h*|))+/im", '\\1' ,  $input );
the above keeps line termination the same as in the source file; can you give it a quick check your side to ensure it works (if you don't mind)? 

modified one that 'cleans' the new lines:
 preg_replace( "/((\r|)\n(\h*|))+/im", PHP_EOL ,  $input );

Nathan

No, no, you missed my meaning... I don't care about line ending... I care about trailing whitespace on non-empty lines. 


modified one that 'cleans' the new lines:
  preg_replace( "/((\r|)\n(\h*|))+/im", PHP_EOL ,  $input );
Yes, this is preferred with respect to line ending IMHO. But it still strips trailing whitesapce.
Almost there... but you've also got that first blank line still hanging around which is supposed to be removed :D 

Cheers,
Rob.

Hi Nathan,
The problem is not mine to speak of necessarily. I was trying to help find a solution for another. But from what I understand, they have a online lesson that they dont want people to be able to log in as another user and get the answers to. 

Here is the their post.

Hi All!
I am looking for a solution, I want a user to do a single Login only on a PC 
.
E.g. If a User has logged on my website website.com in Internet explorer, then he cant login on same website in another browser like Firefox etc with 
same loginid or another.

Can I trace MAC address of a single machine to solve this issue?
Or is there a concept of GLOBAL COOKIE / Cross Browser Cookie which will 
work for all browsers in a single machine..

I hope You will help me out

cool; only effective way i can see is to produce a unique (one time) hash in response to every request, and submit that with the answer; that way it's unique to every interaction. And only allow the test to be taken by a specific login once (ie if they've started it, they can't start again)
But doesn't effectively stop anything because they could have 2 user accounts, and all the previous matters. 

you can make it more difficult, can't prevent it.

as far as I know anyway!

Best,

Nathan

You will have to use flash, but, you can set up a LocalConnection class that determines if the swf is being run on the same system and if it is boot one. You have the LocalConnection class send out a message to itself and if it answers itself, then there are two running. Otherwise only that one is running. Sort of hackish, but would probably do the trick.

You may still have trouble with virtual machines though.

I was given a solution, or a work-around. You will have to use flash, but, you can set up a LocalConnection class that determines if the swf is being run on the same system and if it is boot one. You have the LocalConnection class send out a message to itself and if it answers itself, then there are two running. Otherwise only that one is running. Sort of hackish, but would probably do the trick.

Hi Nathan,
The problem is not mine to speak of necessarily. I was trying to help find a solution for another. But from what I understand, they have a online lesson that they dont want people to be able to log in as another user and get the answers to. 

Here is the their post.

Hi All!
I am looking for a solution, I want a user to do a single Login only on a PC 
.
E.g. If a User has logged on my website website.com in Internet explorer, then he cant login on same website in another browser like Firefox etc with 
same loginid or another.

Can I trace MAC address of a single machine to solve this issue?
Or is there a concept of GLOBAL COOKIE / Cross Browser Cookie which will 
work for all browsers in a single machine..

I hope You will help me out

hi all,

$results is a xml format string,
I want to get this string as a real xml file
$nodes = simplexml_load_file($results);
but $nodes is empty array...

nodes must be an object contains xml


Thanks,
