So in the file it would look like (from the original file the user uploads that is) 1 2 3 4 5 6 but when the file is saved to the server it must look like 1 2 3 4 5 6
If that is all (i.e., removing double linefeeds), then this will do it: $text_array = array(); $text_array = explode("\n\n", $input_text); $output_text = implode("\n",$text_array);
Sorry tedd, this is broken. It doesn't solve problems with runs of greater than 2 newlines which is even in the example :) I would use the following instead which is also line break agnostic with final output in the style for your system: <?php $data = preg_replace( "#[\r\n]+#", PHP_EOL, $input ); ?> Cheers, Rob. -- E-Mail Disclaimer: Information contained in this message and any attached documents is considered confidential and legally protected.
