The following snippet is untested and using Ash's regex (it is accurate
\s matches any white space). $content is what is getting stripped of the
new lines and $filtered is the cleansed output. See if that does the
trick for you.
$lines = str_split(PHP_EOL, $content);
$filtered = '';
foreach ($lines as $line) {
if (!preg_match('^\s*$', $line)) {
// Splitting on the PHP_EOL characters cause it to be removed be
sure to put it back
$filtered .= $line . PHP_EOL;
}
}

I thing must be something with the /../sm attributes to the regex, spend
like half an hour, but didn't get it, I'm running against a dead line,
doesn't seem to be that easy if regex is not the everydays need u have

Hi all, I'm a bit under stress, maybe somebody knows the regex on a

using PHP_EOL would be great.

The regex that would match a line containing only whitespace would
look
like this:
^\s*$

Are the lines actually whitespace, or are they actually <br/> tags that
are inserting lines to format the page for HTML display?
