The DateTime::createFromImmutable Method

The static method createFromImmutable of the DateTime class creates a new mutable DateTime object based on an immutable DateTimeImmutable object.

Syntax

DateTime::createFromImmutable(DateTimeImmutable $object): DateTime

Example

Let's create a mutable DateTime object from an immutable one:

<?php
	$immutable = new DateTimeImmutable('2023-07-15');
	$mutable = DateTime::createFromImmutable($immutable);
	echo $mutable->format('Y-m-d');
?>

Code execution result:

'2023-07-15'

Example

Let's demonstrate the difference between mutable and immutable objects:

<?php
	$immutable = new DateTimeImmutable('2023-07-15');
	$mutable = DateTime::createFromImmutable($immutable);
	
	$mutable->modify('+1 day');
	$newImmutable = $immutable->modify('+1 day');
	
	echo $mutable->format('Y-m-d') . "\n";
	echo $newImmutable->format('Y-m-d');
?>

Code execution result:

'2023-07-16'
'2023-07-16'

Example

Creating a mutable object with a time zone:

<?php
	$timezone = new DateTimeZone('Europe/Moscow');
	$immutable = new DateTimeImmutable('now', $timezone);
	$mutable = DateTime::createFromImmutable($immutable);
	echo $mutable->format('Y-m-d H:i:s e');
?>

Code execution result:

'2023-07-15 14:30:00 Europe/Moscow'
