I would try this $lines = preg_split('|[\n\r]|', $content); $filtered = ''; foreach ( $lines as $line ) { $txt = trim( $line ); if ( ! empty( $txt ) ) { $filtered .= $line; } } It is much more intense to do the preg_match inside a loop. You should only do it once, then use less intense function calls inside the loop. warning: completely untested... have no example input you are using... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] how to strip empty lines out of a txt using preg_replace()
and this is the PHP_EOL solution: $dtd = preg_replace( "/[". PHP_EOL . "]+/", "". PHP_EOL . "", $dtd); dont ask me why two empty strings are needed to surround the PHP_EOL but its does it. Why this works? we have got an INTERPRETER here any \n is transtlated into 0x0D an \r into 0x0A so the pattern does not reach prce as '\n' hehe "Martin Scotta" wrote in message news:6445d94e0909040653i44716f79m972f11055599...@mail.gmail.com... > On Fri, Sep 4, 2009 at 10:37 AM, Ralph Deffke wrote: > > > the problem is some have got \t\n > > some are just \n\n\n > > > > using PHP_EOL is a must > > > > I thing must be something with the /../sm attributes to the regex, spend > > like half an hour, but didn't get it, I'm running against a dead line, > > doesn't seem to be that easy if regex is not the everydays need u have > > > > > > "Ashley Sheridan" wrote in message > > news:1252071327.24700.152.ca...@localhost... > > > On Fri, 2009-09-04 at 15:28 +0200, Ralph Deffke wrote: > > > > ok > > > > preg_replace( "/^\s*$/m", "", $somestring) > > > > does not take empty lines out > > > > > > > > "Ashley Sheridan" wrote in message > > > > news:1252069539.24700.150.ca...@localhost... > > > > > On Fri, 2009-09-04 at 14:58 +0200, Ralph Deffke wrote: > > > > > > Hi all, I'm a bit under stress, maybe somebody knows the regex on a > > > > snap. > > > > > > using PHP_EOL would be great. > > > > > > > > > > > > thanks > > > > > > ralph_def...@yahoo.de > > > > > > > > > > > > > > > > > > > > > > > The regex that would match a line containing only whitespace would > > look > > > > > like this: > > > > > > > > > > ^\s*$ > > > > > > > > > > Thanks, > > > > > Ash > > > > > http://www.ashleysheridan.co.uk > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > Are the lines actually whitespace, or are they actually tags that > > > are inserting lines to format the page for HTML display? > > > > > > Thanks, > > > Ash > > > http://www.ashleysheridan.co.uk > > > > > > > > > > > > > > > > > -- > > PHP General Mailing List (http://www.php.net/) > > To unsubscribe, visit: http://www.php.net/unsub.php > > > > > The PHP_EOL is system dependent.

Re: [PHP] 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 .
