How can the use of error reporting functions in PHP help in debugging and improving the functionality of a script like the one mentioned in the forum thread?

To improve the functionality of a script and aid in debugging, using error reporting functions in PHP can help identify and resolve issues more efficiently. By enabling error reporting, developers can receive notifications about any errors, warnings, or notices that occur during script execution, allowing them to pinpoint and address issues promptly.

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