To register a variable in PHP session, you need to follow these steps:
Start the PHP session using the session_start() function .
Create a new session variable and assign a value to it. For example, if you want to register a user's name, you can use the following code:
$_SESSION['username'] = 'John Doe';
You can also create an associative array to store multiple values in a session variable . For example:
$_SESSION['user_info'] = array(
'username' => 'John Doe',
'email' => 'john.doe@example.com',
'age' => 30
);
To access the registered session variables later, you need to start the session again and use the same variable names. For example:
session_start();
echo $_SESSION['username']; // Output: John Doe
echo $_SESSION['user_info']['email']; // Output: john.jadoe@example.com
It's important to note that session variables are not stored in the client's browser like cookies. Instead, they are stored on the server and associated with a session ID, which is usually stored in a cookie on the client's browser. This allows you to store sensitive information without exposing it to the client.
