The DateTimeImmutable class

(PHP 5 >= 5.5.0, PHP 7)

Simple usage of DateTimeImmutable Class:

<?php
$format = "Y-m-d";
$dateString = "2015-01-25";

// Get new DateTimeImmutable Object
$date = DateTimeImmutable::createFromFormat($format,$dateString);

var_dump($date);

// DateTimeImmutable object can be used similar to DateTime object
echo $date->format("Y/m/d");
