PHP Sessions Example
Previous PHP tutorial we learnt about session how to create a session, retrieve session and destroy session. In this PHP tutorial we will learn more about session with php form example to create a session and retrieve and destroy session.
PHP Session Exmaple
First, design php form with one textbox control with three buttons, one for create session second for retrieve session and last for destroy session. Here, we first create session using session button. When the create session button clicked then $_SESSION[“sname”] session created with the value of textbox control. after creating session we retrieve the $_SESSION[“sname”] value using view session button. finally we destroy all session using session_destroy() function with click of destroy button. After destroying we try to get $_SESSION[“sname”] values it shows error message like “All Sessions Destroyed !!”.
PHP form for session example like :
<?php
session_start();
?>
<html>
<head>
