Solution

As we know HTTP is a stateless protocol, when a user requests one page, followed by another, HTTP does not provide a way for you to tell that both requests came from the same user. The idea of session control is to be able to track a user during a single session on a website.

First, we create a form with a text field called name and a submit button. Then, we Set the method to post and action to submit.php. The form looks like this-

<form name="form" method="post" action="submit.php">
<label for="name">Name:</label>
<input type="text" name="name" id="name" />
<input type="submit" name="Submit" value="Submit" />
</form>

Create an another page 'submit.php' and insert the following code -

<?php
// initiate session
session_start();
// check that form has been submitted and that name is not empty
if ($_POST && !empty($_POST['name'])) {
// set session variable
$_SESSION['name'] = $_POST['name'];
}
?>
<html>
<head>
<title>Set Session</title>
</head>
<body>
<?php
// check session variable is set
if (isset($_SESSION['name'])) {
// if set, greet by name
echo 'Hi, '.$_SESSION['name'];
echo 'Welcome to this page.';
}
else {
// if not set, send back to login
echo 'Please <a href="form.php">Login</a>';
}
?>
</body>
</html>

In the above example, If $_SESSION['name'] has been set, a welcome message is displayed. Otherwise, the page tells the visitor that it doesn’t recognize the user, and provides a link to login from the first page.
