So, doing this client side would be best so you dont have to use PHP on each postback to check/assign the values..

If you want simple, use jQuery...

here is an example of one way to do this...

<!DOCTYPE html>
<html>
<head>
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js">
 </script>

</head>
<body>
UserName: <input id="txtUsername" type="text" /><br/>
EmpID: <input id="txtEmpID" type="text" />

<script>
$('#txtUsername').keypress(function(){
   $('#txtEmpID').val($('#txtUsername').val())
});

</script>
</body>
</html>
