Please post your code; without that it's very difficult to guess what's going on.

thanks for reply. my code is here......

HTML Code:

<html>
<head>
<script type="text/javascript">
var xmlhttp;
function loadXMLDoc(url)
{
xmlhttp=null;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=state_Change;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}

function state_Change()
{
if (xmlhttp.readyState==4)
  {// 4 = "loaded"
  if (xmlhttp.status==200)
    {// 200 = "OK"
    document.getElementById('T1').innerHTML=xmlhttp.responseText;
    }
  else
    {
    alert("Problem retrieving data:" + xmlhttp.statusText);
    }
  }
}
</script>
</head>

<body onload="loadXMLDoc('test_xmlhttp.txt')">
<div id="T1" style="border:1px solid black;width:300;padding:5"></div><br />
<button onclick="loadXMLDoc('test_xmlhttp2.txt')">Click</button>
</body>

</html>

I don't see anything wrong with your code.

Make sure you have the two files "test_xmlhttp.txt and test_xmlhttp2.txt" in the same directory as your main file.
If they aren't in the same directory, then make sure the path to those files are correct in the code.

Are you saying that test_xmlhttp.txt isn't retrieved?
OR,
The file isn't parsed by PHP?

If it is number 2, change the extension from .txt to .php .
