1. Login page program using PHP and MySQL DB 

a) first create a html page as following.

<html>
<body >
<form method="post" action="userLogin.php" >
<table border="1" >
<tr>
<td>
<B>User-Id</B>
</td>
<td><input type="text" name="userid">
</tr>
<tr>
<td><B>Password</B></td>
<td><input name="password" type="password"></input></td>
</tr>
<tr>
<td><input type="submit" value="Submit">
<td><input type="reset" value="Reset">
</tr>
</table>
</form>
</body>
</html>

b) now create page called “userLogin.php” as following code.

<?php
$f_usr= $_POST["userid"];
$f_pswd= $_POST["password"];
$con=mysql_connect("localhost","root","");
if(!$con)
{
die('Connection Failed'.mysql_error());
}
mysql_select_db("mars_db",$con);
$result=mysql_query("select * from users");
while($row=mysql_fetch_array($result))
{
if(($row["usernm"]==$f_usr) && ($row["password"]==$f_pswd))
{
echo "Welcome";
}
}
?>

2. Program on Session Variables

<?php
error_reporting(E_ALL ^ E_NOTICE);
session_start();
if (!$_SESSION['count'])
$_SESSION['count'] = 0;
if ($_GET['count'] == 'yes')
$_SESSION['count'] = $_SESSION['count'] + 1;
echo "<h1>".$_SESSION['count']."</h1>";
?>
<a href="session.php?count=yes">Click here to count</a>

3. Destroying Sessions using PHP

<?php // start the session
session_start();
header("Cache-control: private"); //IE 6 Fix
$_SESSION = array();
session_destroy();
echo "<strong>Step 5 - Destroy This Session </strong><br />"; if($_SESSION['name'])
{  echo "The session is still active"; }
else
{    echo "Ok, the session is no longer active! <br />";
echo "<a href=\"page1.php\"><< Go Back Step 1</a>";
}
