What are the best practices for debugging PHP code that involves passing variables between pages?

When debugging PHP code that involves passing variables between pages, it's important to ensure that the variables are properly set and passed between the pages. One common practice is to use sessions to store and retrieve variables across different pages in a PHP application. By properly utilizing sessions, you can easily debug and troubleshoot any issues related to passing variables between pages. 

// Start the session
session_start();

// Set a variable in one page
$_SESSION['variable_name'] = 'value';

// Retrieve the variable in another page
$variable = $_SESSION['variable_name'];

// Debug the variable
var_dump($variable);
