This tutorial will explain how to login and logout page using PHP session and database using MySql. This tutorial will explain how to login and logout the web page using PHP session and database using MySql in Hindi. By using this login script, we can show the secure pages after the login page successfully logged in. For the authentication process, we have to create a login page with the username and password input field. By using the input box, we can get the username and password using the PHP post method which is secure after submitting the form. Create the home.php file which has the script to destroy the session. When a user submits their username and password in the login page, the PHP login script will check the given username and password in the database table using MySQL select query, if the query returns the value, the script will redirect to home.php page. If a username or password is the wrong system will show error message like “User Name Or Password Invalid”. Destroy the session once the user clicks the logout link from home.php page.
