Troubleshooting PHP errors becomes easier by enabling the display_errors directive. This setting allows error messages to be shown directly on your web page for debugging purposes.

Steps to Enable:

1. Edit php.ini: Locate and set display_errors = On.
2. Use .htaccess: Add php_value display_errors On.
3. Temporary Script: Add ini_set('display_errors', 1); in your PHP file.

🛑 Important: Always disable display_errors in production to avoid exposing sensitive information.
