How can PHP developers ensure accurate age calculations when dealing with date values, especially in scenarios where data is constantly updated?

When dealing with date values in PHP, especially when calculating ages, it's important to account for leap years and potential timezone differences. To ensure accurate age calculations, developers can use the DateTime object in PHP, which handles date calculations accurately. By using the DateTime object, developers can easily calculate age based on birthdate and current date, taking into consideration leap years and timezone adjustments.

$birthdate = new DateTime('1990-05-15');
$currentDate = new DateTime();
$age = $birthdate->diff($currentDate)->y;
echo "Age: " . $age;
