What steps can be taken to troubleshoot and debug PHP scripts that are throwing fatal errors?

When a PHP script is throwing fatal errors, the first step is to check the error message to identify the specific issue. Common causes of fatal errors include syntax errors, undefined functions or variables, and memory limit exceeded. To troubleshoot and debug the script, you can use tools like error reporting, debugging tools, and logging to track down the root cause of the error.

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

// Check for syntax errors and fix them
// Make sure all functions and variables are defined before use
// Increase memory limit if necessary
ini_set('memory_limit', '256M');
?>
