How can beginners effectively debug PHP code to identify and fix issues like unexpected output or errors?

To effectively debug PHP code for unexpected output or errors, beginners can start by using tools like error reporting, var_dump(), and echo statements to identify where issues are occurring. They can also utilize IDEs with debugging capabilities to step through code and pinpoint errors. Additionally, checking for syntax errors and ensuring proper variable scope can help in resolving problems.

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Code snippet with debugging statements
$variable = 'Hello World';
var_dump($variable);

echo "This is a test";

// More code here
?>
