Firstly, in your program you dont need php... it can be done by using html and javascript..

 

<script language="JavaScript1.2" type="text/javascript">
function copyText(){
if(document.getElementById("txt_text1").value != ''){
	document.getElementById("txt_text2").value = document.getElementById("txt_text1").value;
}else{
	alert("Nothing To Copy");
}
}

</script>

<input type="text" id="txt_text1" name="txt_text1" value="">
<input type="button" name="btn_copy" value="Copy" onClick="copyText()">
<input type="text" id="txt_text2" name="txt_text2" value="">

Here's some commented code on how to do it in php:

<?php
if (!isset($_POST['text1'])) //check to see if first load of page
{
$text2 = '<textarea name="text2" readonly="true"></textarea><br>'; //show empty text area if first load 
}
else{
$text_content = $_POST['text1']; // when not first load assign text from text area1 to this variable
$text2 = '<textarea name="text2" readonly="true">'.$text_content.'</textarea><br>'; //show text area with text from first text area in it
}
echo '<form action="'.$_SERVER['PHP_SELF'].'" method="post" type="submit">'; // reload this page when button is clicked
echo '<textarea name="text1"></textarea>&nbsp'; //make first text area
echo $text2; //make second text area
echo '<input type="submit" value="Move" />'; //make button to perform proccess
echo '</form>'; //end the form
?>
