A PHP CalculateAge() function created by applying the logic we used previously in C# to calculate the age from a given birth date.
1. <?php
2. // $BirthDate expected format is YYYY/MM/DD
3. function CalculateAge($BirthDate)
4. {
5. // Put the year, month and day in separate variables
6. list($Year, $Month, $Day) = explode("/", $BirthDate);
7.
8. $YearDiff = date("Y") - $Year;
9.
10. // If the birthday hasn't arrived yet this year, the person is
one year younger
11. if(date("m") < $Month || (date("m") == $Month && date("d") <
$DayDiff))
12. {
13. $YearDiff--;
14. }
15. return $YearDiff;
16. }
17.
18. // How to use the function
19. echo CalculateAge("1986/06/18");
20. ?>
