<?php  //date in mm/dd/yyyy format; or it can be in other formats as well  $birthDate = "12/17/1983";  //explode the date to get month, day and year  $birthDate = explode("/", $birthDate);  //get age from date or birthdate  $age = (date("md", date("U", mktime(0, 0, 0, $birthDate[0], $birthDate[1], $birthDate[2]))) > date("md")    ? ((date("Y") - $birthDate[2]) - 1)    : (date("Y") - $birthDate[2]));  echo "Age is:" . $age;?>
