在文本框中显示两个值

I'm trying to display two values in a textbox but the value should be next line. here is my sample query. here i tried
also its not working. give me a idea to display in a next line.... thank you..

</head>
<?php 
$s='hi';
?>
</br>
<?php
$d='how are you';
?>
<body>
<form id="form1" name="form1" method="post" action="">
  <label>
  <input type="text" name="textfield" value="<?php echo $s."<br />"; echo $d?>" id="textfield" />
  </label>
</form>

Use a textarea, and line breaks instead of <br> elements.

 <textarea name="textfield"><?php echo $s."
".$d; ?></textarea>

to output the contents of the textarea in a HTML document with proper line breaks, use nl2br().

You cannot display line breaks in textfields (input type="text"). You will need a <textarea> for that.

Use <textarea><?php echo $s." ".$d; ?></textarea>

You should use

<textarea><?php echo $s."
"; echo $d?></textarea>

instead of

<input type="text"

because textbox supports only single-line text
