To troubleshoot and resolve a "FATAL ERROR: Incorrect date value" issue in PHP, you can ensure that the date format being passed to functions like `date()` or `strtotime()` is in a valid format. This error typically occurs when the date string does not match the expected format, causing PHP to throw an error.

echo $date->format('Y-m-d'); // Output the formatted date
