How can a beginner in PHP effectively troubleshoot and debug code errors?

To effectively troubleshoot and debug code errors in PHP 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 var_dump() or print_r() to inspect variables and their values during runtime. Finally, utilizing an integrated development environment (IDE) with debugging tools can help step through code and identify issues more efficiently. 

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

// Sample code with a potential error
$number = 10;
$sum = $number + $undefinedVariable;

// Print variable values for debugging
var_dump($number);
var_dump($sum);
?>
