How to convert PHP MongoDB BSON Binary to (L)UUID or ObjectId

functions.php

<?php

use MongoDB\BSON\Binary;
use MongoDB\BSON\ObjectId;

function mongoBinaryToUuid(Binary $bin): string
{
    $hex = bin2hex($bin->getData());

    return substr($hex, 0, 32);
}

function mongoBinaryToObjectId(Binary $bin): ObjectId
{
    $hex = bin2hex($bin->getData());

    return new ObjectId(substr($hex, 0, 24));
}

Requires PHP mongodb extension - not sure if this will work with the mongo legacy extension.
