This function allows the addition of day(s),month(s),year(s) to the original date while still preserving the Hours, minutes and seconds

You can also modify to add to hours, miuntes and even seconds.

 

<?php

function add_date($givendate,$day=0,$mth=0,$yr=0) {

      $cd = strtotime($givendate);

      $newdate = date('Y-m-d h:i:s', mktime(date('h',$cd),

    date('i',$cd), date('s',$cd), date('m',$cd)+$mth,

    date('d',$cd)+$day, date('Y',$cd)+$yr));

      return $newdate;

              }



?>

Just add month(s) on the orginal date.





<?php


function add_date($orgDate,$mth){


  $cd = strtotime($orgDate);


  $retDAY = date('Y-m-d', mktime(0,0,0,date('m',$cd)+$mth,date('d',$cd),date('Y',$cd)));


  return $retDAY;


}


?>
