What is the method to register a variable into a session?

by
  1. <?php
  2. Session_register($ur_session_var);
  3. ?>

To register a variable into a session in PHP, you would typically use the $_SESSION superglobal array. Here’s the basic method:

php
<?php
// Start the session
session_start();

// Set session variables
$_SESSION['variable_name'] = $value;
?>

This code initializes the session (if not already started) using session_start(), then assigns a value to a session variable using the $_SESSION superglobal array, with a chosen key ('variable_name' in this example). Later on, you can access this variable throughout the user’s session using $_SESSION['variable_name'].

It’s worth noting that session_start() should be called before any output is sent to the browser, preferably at the beginning of your script.
