last.php is taking $_POST values that to not exist in page3.php thereby overwriting the $_SESSIONS
Remove from last.php:

$_SESSION['value'] = $_POST['value'];
$_SESSION['value2'] = $_POST['value2'];
$_SESSION['value3'] = $_POST['value3'];

And your values should remain in tact.

No remove the lines from last from last.php

You pasted this

//last.php

<?php
session_start();
$_SESSION['value'] = $_POST['value'];
$_SESSION['value2'] = $_POST['value2'];
$_SESSION['value3'] = $_POST['value3'];
$submit = $_POST['submit'];
?>

Those 3 lines are resetting your $_SESSION values at the top of the page making them empty because $_POST etc do not exist

Hi, You mean
$_SESSION = $_POST;
$_SESSION = $_POST;
$_SESSION = $_POST;

I was getting ahead of myself - this is how your code should work:

//page1.php
<?php
session_start();
$_SESSION['value'] = $_POST['value'];

?>
<body>
<h2 align="center" style="font-size:xx-large; color:#F06">Use of Session</h2>
<form action="page2.php" method="post" id="page2" name="page2" enctype="multipart/form-data">
<table align="center" >
<tr>
<td>Enter the Value :</td>
<td><input type="text" name="value" id="value" /></td>
</tr>
<tr><td align="center"><input type="submit" name="submit" id="submit" value="submit" /></td>

</tr>
</table>
</form>
</body>

//page2.php
<?php
session_start();
$_SESSION['value'] = $_POST['value'];

//submit = $_POST['submit'];
//if(!empty($submit))
//{
//echo "value of textbox".$_SESSION['value'];
//}

?>
<body>
<h2>Use of Session</h2>
<form action="page3.php" method="post" id="page2" name="page2" enctype="multipart/form-data">
<table >
<tr>
<td>Enter the Value :</td>
<td><input type="text" name="value2" id="value2" /></td>
</tr>
<tr><td colspan="2">&nbsp;</td></tr>
<tr><td colspan="2">&nbsp;</td></tr>
<tr><td align="center"><input type="submit" name="submit" id="submit" value="submit" /></td>
</tr>
</table>
</form>
</body>

//page3.php

<?php
session_start();
$_SESSION['value2'] = $_POST['value2'];
$submit = $_POST['submit'];
//if(!empty($submit))
//{
//echo "value of First Page :"."<br/>".$value."<br/>"."<br/>";
//echo "value of Second Page :"."<br/>".$_SESSION['value2']."<br/>"."<br/>";
//echo "value of Third Page :"."<br/>".$_SESSION['value3'];
//}

?>
<body >
<h2 align="center" style="font-size:xx-large; color:#F06">Use of Session</h2>
<form action="last.php" method="post" id="page3" name="page3" enctype="multipart/form-data">
<br/>
<br/>
<br/>
<table>
<tr>
<td>Enter the Value :</td>
<td><input type="text" name="value3" id="value3" /></td>
</tr>
<tr><td align="center"><input type="submit" name="submit" id="submit" value="submit" /></td>

</tr>
</table>
</form>
</body>

//last.php

<?php
session_start();
$_SESSION['value3'] = $_POST['value3'];
$submit = $_POST['submit'];
?>

<td>Value3</td></tr>
<tr>
<?php if(!empty($submit))
{
?>
<td><?php echo $_SESSION['value']; ?></td>
<td><?php echo $_SESSION['value2']; ?></td>
<td><?php echo $_SESSION['value3']; ?></td>
<?php
}
?>
<tr><td colspan="2" align="center"><input type="submit" name="submit" value="submit" id="submit" /></tr>
</table>
</form>
</body>

i removed it from last.php like following

<?php
session_start();
/*$_SESSION = $_POST;

//$_SESSION = $_POST;
//$_SESSION = $_POST;
$submit = $_POST;
