Not even close :)

<?php
$input = 'blah b asd as d
asd
a
sd
da
asd
d
asd
da';
echo preg_replace( "/(\s)\s+/im", '\\1', $input );
on PHP/5.2.8 produces:
blah b asd as d asd
a
sd
da asd

asd

unless I'm completely missing the elephant in the room here!
Doesn't appear to work on the following:
$input = '
1
2
3
4
5
6';
Additionally, your solution modifies lines that weren't asked to be
modified :) I realize it potentially makes for a more succinct
solution (if you ever get it to work properly in the general case)
but it is not a valid solution for the requested functionality-- The
OP did not ask for trimming of lines with content ;)

but when the file is saved to the server it must look like
1

the above produces what's required; and hence the vertical whitespace
only solution included too "/(\h)\h+/im"
what version are you on btw? not being an ass and actually am
interested in where it doesn't work (as I use the code on some
important sites & in some apps that are open sourced)
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 );
Best,
Nathan
