Are there specific debugging techniques or tools that can help identify and fix issues with sessions and form elements in PHP?

One common issue with sessions and form elements in PHP is when session data is not being properly stored or retrieved, leading to errors or unexpected behavior. To debug and fix this issue, you can use tools like `var_dump($_SESSION)` to check the session data, and `var_dump($_POST)` to check the form data being submitted. Make sure to properly initialize the session at the beginning of your script using `session_start()`.

// Start the session
session_start();

// Check session data
var_dump($_SESSION);

// Check form data
var_dump($_POST);

// Your PHP code here to handle sessions and form elements
