Textarea scroll bar

Question

I want the following textarea to allow scrolling when the stuff inside text.txt fills up more than the textarea window. Also, I want it to auto scroll to the bottom of textarea field. Is this possible?

<textarea class="textarea" id="textarea" readonly="readonly" " rows="20">
      <?php
      //$date=date(dmY);
      $file = fopen("text.txt", "r");

      while(!feof($file)){
         echo fgets($file);
      }
      fclose($file);
    ?>
    </textarea>

Thanks.

This is the CSS that will make sure you get a vertical scrollbar when there is too much text in:

overflow: auto;

For scrolling to bottom of textarea, clearly you need JS for that. See this problem.
