Set and retrieve a session in php
To set a session in PHP use the code below:

<html>
<body>
<?php
// Set session variables
$_SESSION["username"] = "john2023";
$_SESSION["logged"] = "yes";

echo "Your username is " . $_SESSION["username"] . ".<br>";
echo "You are logged in " . $_SESSION["logged"] . ".";
?>
</body>
</html>

To update a session in PHP we use the same code just change the values:
<?php
// Start the session
session_start();
?>
<!DOCTYPE html>
<html>
<body>

// Set session variables
$_SESSION["username"] = "john2024";
$_SESSION["logged"] = "yes";
