Handling MongoDB Dates in PHP (New Driver)

In case you’re enthusiastic like me and wanted to use the new MongoDB driver for PHP ASAP, you’ve might have stumbled upon differences in date handling.

Untill now, when you’ve wanted to properly insert dates, you’d construct new MongoDate and insert it as such. Well, there is no such class any more in the new driver, and to insert a date properly, you need to use new MongoDB\BSON\UTCDatetime. Notice the difference in constructor arguments, though — the new UTCDateTime accepts Unix timestamp in milliseconds, not seconds like MongoDate did.

Of course, you have the use the new class when querying as well:

$docs = $collection->find([
'ts' => [
'$gt' =>new MongoDB\BSON\UTCDatetime($unix_timestamp * 1000)

And when you fetch your objects, you can use toDateTime to get native PHP’s DateTime and format it as you’d like.
