In what scenarios should PHP developers avoid using for loops for age calculation and instead opt for alternative methods to ensure accurate results?

When calculating age using for loops in PHP, developers should avoid relying solely on the number of years passed since the birth year. This method can lead to inaccuracies, especially when considering leap years and the current date. Instead, developers should utilize PHP's built-in DateTime class to accurately calculate age based on the birthdate. 

$birthdate = new DateTime('1990-05-15');
$currentDate = new DateTime();
$age = $currentDate->diff($birthdate)->y;

echo "The person's age is: " . $age;
