Example 1: Below programs illustrate the DateTimeImmutable::createFromMutable() function in PHP.
PHP
<?php $dateTime = new DateTime("2020-04-12"); var_dump(DateTimeImmutable::createFromMutable($dateTime)); ?> |
Output:
object(DateTimeImmutable)#2 (3) {
["date"]=>
string(26) "2020-04-12 00:00:00.000000"
["timezone_type"]=>
int(3)
["timezone"]=>
string(3) "UTC"
}
Example 2:
PHP
<?php // Creating a new DateTime::add() object $datetime = new DateTime("2019-10-03T10:00:00"); var_dump(DateTimeImmutable::createFromMutable($datetime)); // Creating a new DateTimeImmutable() object $datetime = new DateTime(); // Initialising year, month and day $Year = '2019'; $Month = '10'; $Day = '03'; // Calling the DateTimeImmutable::setDate() function $datetime = $datetime->setDate($Year, $Month, $Day); var_dump(DateTimeImmutable::createFromMutable($datetime)); ?> |
Output:
object(DateTimeImmutable)#2 (3) {
["date"]=>
string(26) "2019-10-03 10:00:00.000000"
["timezone_type"]=>
int(3)
["timezone"]=>
string(3) "UTC"
}
object(DateTimeImmutable)#1 (3) {
["date"]=>
string(26) "2019-10-03 20:35:03.000000"
["timezone_type"]=>
int(3)
["timezone"]=>
