$pass=$_REQUEST['password'];
$sel=mysql_query("select * from login_detail where USERNAME='$id' AND PASSWORD='$pass'")or die(mysql_error());
if($arr=mysql_fetch_array($sel))
{
if(($id==$arr['USERNAME']) && ($pass==$arr['PASSWORD']))
{
session_start();
$_SESSION['id']=$id;
$query = "SELECT * FROM student_personal";
$result = mysql_query($query) or die(mysql_error());
if($result)
{
$_SESSION['allStudent']['']= mysql_fetch_array($result);
}
header("location: viewPages/common/main.php?active=dashboard");

<?php
if(isset($_SESION['allStudent']))
{
echo "------------------------------------------<br>";
echo "Student Name--------------------------- DOB<br>";

while($row = mysql_fetch_array($_SESSION['allStudent']))
{
echo $row['STUDENT_NAME']." --------------".$row['DOB']."<br>";

Table Name : student_personal
`SR_NUMBER` int(11) NOT NULL,
`STUDENT_NAME` varchar(30) NOT NULL,
`GENDER` int(11) NOT NULL,
`DOB` varchar(25) NOT NULL,
`RELIGION` varchar(30) NOT NULL,
`MAILING_ADDRESS` text NOT NULL,
`TELEPHONE_NO` varchar(22) default NULL,
`MOBILE_NO` varchar(25) default NULL,
`EMAIL` varchar(30) default NULL,
`PERMANENT_ADDRESS` text,
`MOTHER_TONGUE` varchar(30) default NULL,
`CATEGORY` int(11) default NULL,
`STATUS` int(11) NOT NULL default '1',
`REG_DATE` date NOT NULL,
`FIRST_NAME` varchar(25) NOT NULL,
`LAST_NAME` varchar(25) NOT NULL,

session_start();
$_SESSION['count'] = 1;
$_SESSION['record'][$_SESSION['count']] = array();
$query //retrive ur data here
$result set of ur query
while ($row = mysql_fetch_assoc($result))
{
$_SESSION['record'][$_SESSION['count']]['SR_NUMBER'] = $row["SR_NUMBER"];
$_SESSION['record'][$_SESSION['count']]['STUDENT_NAME'] = $row["STUDENT_NAME"];
$_SESSION['record'][$_SESSION['count']]['GENDER'] = $row["GENDER"];
$_SESSION['record'][$_SESSION['count']]['DOB'] = $row['DOB'];
...// and go on
$_SESSION['count'] = $_SESSION['count'] + 1;
}
foreach($_SESSION['record'] as $key => $value)
{
echo $value['SR_NUMBER'];
echo $value['STUDENT_NAME'];
echo $value['GENDER'];
echo $value['DOB'];
....
}
