How can you effectively debug PHP scripts to identify and resolve issues?

To effectively debug PHP scripts, you can use tools like Xdebug or PHP's built-in error reporting functions. You can also use var_dump() or print_r() functions to output variable values and check for any unexpected results. Additionally, breaking down the code into smaller parts and testing each part individually can help pinpoint the issue. 

<?php
// Example code snippet to demonstrate debugging in PHP
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Sample code with a potential issue
$number1 = 10;
$number2 = 0;
$result = $number1 / $number2;

// Debugging to identify the issue
var_dump($result);
?>
