Re: how to strip empty lines out of a txt using preg_replace()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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;
   }
}

the problem is some have got \t\n
some are just \n\n....\n

using PHP_EOL is a must

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

 preg_replace( "/^\s*$/m", "", $somestring)
does not take empty lines out

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

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?
