How can HTTP requests impact the state of PHP classes and variables in a web application?

HTTP requests can impact the state of PHP classes and variables in a web application by potentially resetting or altering their values. To maintain the state of PHP classes and variables between requests, you can use sessions to store and retrieve data across multiple requests. 

// Start a session to maintain state between HTTP requests
session_start();

// Store data in session variables
$_SESSION['example_variable'] = 'value';

// Retrieve data from session variables
$example_variable = $_SESSION['example_variable'];
