How can a beginner in PHP effectively debug and troubleshoot code that is not functioning as expected?

To effectively debug and troubleshoot PHP code as a beginner, you can start by using error reporting functions like error_reporting(E_ALL) and ini_set('display_errors', 1) to display any errors or warnings. Additionally, you can use tools like var_dump() or print_r() to inspect variables and their values at different points in your code. Another helpful technique is to break down your code into smaller parts and test each part individually to isolate the issue. 

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Example code snippet to troubleshoot
$number = 5;
$sum = $number + '10'; // This will cause a type mismatch error

// Display error message
var_dump($sum);
?>
