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

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;

} } Ralph Deffke wrote:

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 "Ashley Sheridan" <ash@ashleysheridan.co.uk> wrote in message news:1252071327.24700.152.camel@localhost...

Hi all, I'm a bit under stress, maybe somebody knows the regex on a
          
snap.
      
using PHP_EOL would be great.

thanks ralph_deffke@yahoo.de

The regex that would match a line containing only whitespace would

look

like this: ^\s*$ Thanks, Ash http://www.ashleysheridan.co.uk

Are the lines actually whitespace, or are they actually <br/> tags that are inserting lines to format the page for HTML display? Thanks, Ash http://www.ashleysheridan.co.uk
