This function will take the date of birth in a time format (from mktime() function) and convert it into age in years, months, and days.

<?php
function get_Age($DOB){

                                $dayinseconds = 24 * 60 * 60;

                                $dayinYear = 0.00273972602739726;

                                

                                $dif = time() - $DOB;

                                

                                $age_in_days = $dif/$dayinseconds;

                                

                                $flt_year = $age_in_days * $dayinYear;

                                $year= floor($flt_year);

                                

                                $flt_month = ($flt_year - $year) * 12;

                                $month = floor($flt_month);

                                

                                $flt_day = ($flt_month - $month) * 30.58;

                                $day = floor($flt_day);

                                

                                return "$year yrs, $month mnths and $day days";

                            } 
?>
