    Consider that in part of writing into file add "\n" at the end, that way its gonna pack it line by line and would be much easier to read just one line.
    In that case you can count lines and take one from the beginning of the file or from its end, depending to where its writing into file.

      But there's a way to read it as it is.. I've seen it somewhere

        PHP Code:
        <?php
        $File         = 'test.txt';
        $End_File = file($File);
        for(        $k = 0; $k<count($End_File); $k++)
        {        /** we do nothing here, we just wanted to get to end of file for info. */}
        preg_match('/(.*?)\|(.*?)\|(.*?)\|(.*?)\|(.*?)\|(.*?)/i', $End_File[$k-1], $matches);
        $Latest_Post = $matches[1].': '.$matches[2];
        echo         $Latest_Post;
        ?>
        ///
        //
        and if you wanted to read the info backwards. you could use array reverse
        PHP Code:
        $End_File = array_reverse(file($File));
        ///
        // 
        heres a temp link to it working.
        http://codemafia.uk.to/test.php


        how it works.
        used count to get to end of file.
        used preg match to match the data input set with |
        then echo'd first 2 matches only. name/message.
        <?php
        include ('Ghost');
        if ($Post == true) {
        echo '

        sigpic
        alt='coding-talk.com!!' />';
        echo 'Sharing Is Caring!';
        } else {
        echo '

        alt='the username GHOST has been comprimised!' />';
        echo 'OMG SOMEBODY HELP ME!!';
        }
        ?>

              the shoutbox ***** is as a result of ur code.. I later spiced it up with substr(); for emotions and wordwrap to manage page width..
              Wish I can find a good logo maker now

                  In the case of adding \n at writing...

                  PHP Code:
                  foreach (explode('|', end(file('file.txt'))) as $k => $v) echo $v.'<br/>';

                    That's basic..
                    I was just confused in the case of many symbols..
                    Thanx anyway..!

                        i believe his code for writting the data to text file already adds the \n for new lines.
                        his text file he supplied for this was actually all on new lines which you wouldnt see as \n is invisible once added to txt file.. it just doesnt look like here on forum due to forum codebox wordwrapping the data when displayed. ;)

                          I can't believe, i need the code to see it and by the posted content of the file i just assumed that.
                          Thats why i insist on posting codes when asking for help about the same code.
                          In the future i will delete any such thread as it is stupid, i doubt that here are some psychics...
                          Anyway, even better if it does add new line already.

                            yeah at first even i didnt think it was new lines. i also thought it was 1 full line being seperated by alot of | (pipelines)
                            but once i copied and pasted the text to my computer i noticed it was all on seperate lines and it made my job of making a piece of code to read it alot more easier.
