What are some recommended resources or tutorials for learning how to calculate age using PHP?

To calculate age using PHP, you can subtract the birth year from the current year and then adjust for the birth month and day if necessary. One way to do this is by using the DateTime class in PHP, which provides methods for working with dates and times. 

// Calculate age using PHP DateTime class
function calculateAge($birthDate) {
    $today = new DateTime();
    $diff = $today->diff(new DateTime($birthDate));
    return $diff->y;
}

// Example of calculating age
$birthDate = '1990-05-15';
$age = calculateAge($birthDate);
echo "Age: " . $age;
