How can PHP code be structured to automatically update a person's age on a specific date each year?

To automatically update a person's age on a specific date each year, you can calculate the age based on their birthdate and the current date, and then update it if the current date matches the specific date each year. This can be achieved by comparing the current date to the specific date each year and updating the age accordingly. 

// Get the person's birthdate
$birthdate = new DateTime('1990-01-01');

// Get the current date
$currentDate = new DateTime();

// Check if the current date matches the specific date each year (e.g. January 1st)
if ($currentDate->format('m-d') == '01-01') {
    // Calculate the age based on the birthdate and current date
    $age = $birthdate->diff($currentDate)->y;
    
    // Update the person's age
    // This could involve updating a database record or displaying the updated age
    echo "Happy Birthday! You are now $age years old!";
}
