Dude its not that difficult:

Code:

<?php
    $futuredate = strtotime("365 days");
    echo date("F d, Y", $futuredate);
?>

My suggestion to you before you post queries here would be to give it a teeney weeney bit of research....GL with translating the date to your preferred output format.

If your date is a unix timestamp just do

Code:

// constants.php
define('YEAR_IN_SECONDS',31556926);
// somewhere in your code
$expiryDate= date("d-m-Y",$date+YEAR_IN_SECONDS);

unix timestamps are just numbers so date calculations should be calculations instead of function calls.
