How can a PHP beginner effectively troubleshoot and debug issues with PHP scripts on a website?

To effectively troubleshoot and debug PHP scripts on a website as a beginner, you can start by enabling error reporting in your PHP script using the error_reporting() function. This will help you identify any syntax errors or runtime errors in your code. Additionally, you can use var_dump() or print_r() functions to output the values of variables at different points in your script to track their values and identify any unexpected behavior. 

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

// Use var_dump() to output variable values
$variable = "Hello World";
var_dump($variable);

// Use print_r() to output array values
$array = [1, 2, 3];
print_r($array);
?>
