    The DateTimeImmutable class

    Introduction

    This class behaves the same as DateTime except it never modifies itself but returns a new object instead.

    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");
