As the type of the first parameter is string, we can assign a relative date for it.
Example:
<?php
$immutable = new DateTimeImmutable('-1 year', new DateTimeZone('Asia/ShangHai'));
echo $immutable->format('Y-m-d H:i:s');
?>
It looks like the parameter of function strtotime and is very helpful for us to get an immutable relative DateTime object.
DateTimeImmutable::__construct
date_create_immutable
(PHP 5 >= 5.5.0, PHP 7)
DateTimeImmutable::__construct -- date_create_immutable — 新しい DateTimeImmutable オブジェクトを返す
説明
オブジェクト指向型
public DateTimeImmutable::__construct
([ string
$datetime = "now"
[, DateTimeZone $timezone = NULL
]] )手続き型
date_create_immutable
([ string
$datetime = "now"
[, DateTimeZone $timezone = NULL
]] ) : DateTimeImmutableDateTime::__construct() と似ていますが、 DateTimeImmutable で動作します。
