In what scenarios should developers avoid manually concatenating date components in PHP and opt for built-in functions instead?

Developers should avoid manually concatenating date components in PHP when they need to manipulate or format dates, as this can lead to errors and inconsistencies. Instead, they should use built-in PHP functions like date() or DateTime to ensure accurate and reliable date handling. 

// Avoid manually concatenating date components
$date = $year . '-' . $month . '-' . $day;

// Use built-in PHP functions instead
$date = date('Y-m-d', strtotime($year . '-' . $month . '-' . $day));

// Or using DateTime class
$date = DateTime::createFromFormat('Y-m-d', $year . '-' . $month . '-' . $day)->format('Y-m-d');
