What are best practices for debugging PHP code when encountering issues with arrays and sessions?

When encountering issues with arrays and sessions in PHP, a common problem could be accessing or manipulating session variables within an array. To debug this, ensure that the session_start() function is called at the beginning of the script and that session variables are properly set and accessed using $_SESSION['key']. Additionally, check for any syntax errors or misspelled keys in the array. 

<?php
session_start();

// Set a session variable within an array
$_SESSION['user'] = array(
    'name' => 'John Doe',
    'email' => 'johndoe@example.com'
);

// Access the session variable within the array
echo $_SESSION['user']['name'];
?>
