PHP Version

Example1

Following example demonstrates the usage of date_timestamp_set() function -

<?php
   $date = new DateTime();
   $res = date_timestamp_set($date, 1505292545);   
   print("Date: ".date_format($res, "Y/m/d H:i:s"));
?>

Example2

The following example creates a DateTime object and modifies its time value using the built-in PHP date_timestamp_set() Function -

<?php
   $date = new DateTime();
   $timestamp1 = time() - (23*12*30);   
   $res1 = date_timestamp_set($date, $timestamp1);      
   print("Date: ".date_format($res1, "Y/m/d H:i:s"));
   print("\n");
   $timestamp2 = time() + (23*12*30);
   $res2 = date_timestamp_set($date, $timestamp2);  
   print("Date: ".date_format($res2, "Y/m/d H:i:s"));
?>

Date: 2020/05/11 08:57:30

Example3

As an alternative to this function you can just pass the time stamp value as a string preceded by "@" as a parameter to the DateTime construct -

  $date = new DateTime("@1495283256");
   print("Date: ".date_format($date, "Y/m/d H:i:s"));?>
