Are there any specific PHP functions or methods that can simplify the process of passing and manipulating variables between PHP pages?

To simplify the process of passing and manipulating variables between PHP pages, you can use sessions in PHP. Sessions allow you to store variables that can be accessed across different pages during a user's visit to a website. This can be useful for passing data between pages without the need to constantly pass variables through URLs or forms. 

// Start the session
session_start();

// Set a session variable
$_SESSION['username'] = 'JohnDoe';

// Access the session variable on another page
session_start();
echo $_SESSION['username'];
