调整回显文本的大小

Question

I have a page that displays text the user typed in a form before that. If the user types a lot in the form and submits, the page that displays the text has a horizontal scroll bar. How could I make the text automatically do a line break after the text fills the screen? It needs to be 8.5 x 11 so it will print. What should I do to the textbox/display page? Here's some code I used:
text area:

<textarea name="body" id="textarea">

display page:

  <h3>
    <?php echo "$body"; ?> <br />
    </h3>

When the text is sent using post and get, it is encoded and decoeded. Thanks..

You can use wordwrap() to get it done on the PHP side.

But you could just use a div with a predefined width:

<h3 style="width: 8.4in;">
    <?php echo "$body"; ?> <br />
