MongoDate toDateTime() function is not defined? - php

Question

This is stumping me... I'm using the exact example from:
http://php.net/manual/en/mongodate.todatetime.php
but I'm getting:
PHP Fatal error: Call to undefined method MongoDate::toDateTime()
<?php
$d = new MongoDate(strtotime("2014-11-18 11:01:25"));
var_dump($d);
var_dump( $d->toDateTime() );
?>
The exact output I get is:
object(MongoDate)#1 (2) {
["sec"]=>
int(1416330085)
["usec"]=>
int(0)
}
PHP Fatal error: Call to undefined method MongoDate::toDateTime() in /xxx/testmongodate.php on line 5
PHP version:
$ php -v

I have been successfully using this installation to insert into and read from an actual mongo database, but now I'm trying to work with MongoDate objects as they are read out of mongo, trying to format them for insert into another database... that is why I'm looking to use this method... but it doesn't seem to be found... ??

Answer 1

For anybody coming to this question late (as I did), the likely issue is that the PHP is using a different Mongo driver. There are currently 2 and the below code is for the legacy driver.
The solution with the legacy driver is to get the date from the Mongo Date using the PHP date function:
<?php
$d = new MongoDate(strtotime("2014-11-18 11:01:25"));
$newdate = date('Y-m-d H:m:s',$d->sec);
var_dump( $newdate );
?>
