How can error handling and debugging techniques be implemented effectively in PHP scripts to identify and resolve issues like the one described in the forum thread?

Issue: The forum thread describes a problem where a PHP script is throwing an undefined variable error. To solve this issue, we can implement error handling and debugging techniques in PHP to identify and resolve such errors. Code snippet:

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

// Define the variable to avoid undefined variable error
$variable = '';

// Your existing code here
?>
